Light emitting panel assemblies include a light emitting panel member having a uniform or variable pattern of light extracting deformities of well defined shapes in or on one or more surface areas of the light emitting panel member. The size and shape as well as the depth and angular orientation and position or location of the light extracting deformities may vary along the length and/or width of a panel surface area to obtain a desired light output distribution from the panel surface area. Also, at least some of the deformities may have planar surfaces in parallel spaced relation to a panel surface area. A focused light source may be insert molded or cast within a light transition area of the light emitting panel member to focus the light on an input surface of the light transition area with predetermined ray angles to fit a particular application. Molded supports may be provided on the panel member for supporting other parts or components in spaced relation therefrom. In another embodiment of the invention, an array of light sources may be mounted on a printed circuit board for directing light through a diffuser or lens mounted in spaced relation to the light sources for use in phototherapy treatment or the like.

A light direction switching apparatus and method is described. The light direction switching apparatus comprises a passive birefringent lens (138), e.g. a birefringent lenticular screen, and a switchable polariser (146). By switching the polariser (146), different directional distributions of output light are provided. The light direction switching apparatus may be used with or incorporated in a display device, such as a liquid crystal display device, to provide a display device switchable between a two dimensional mode and an autostereoscopic three dimensional mode, or to provide a multi-user display device where different images are displayed to different viewers. The light direction switching apparatus may also be used to provide switchable brightness enhancement of reflective or transflective display devices. The light direction switching apparatus may also be used to provide a fibre-optic switching apparatus. The switchable polariser may be mechanically switchable or electrically switchable.

The present invention provides OLEDs of the top emission type comprising organic light-emitting (LE) elements by preventing the problems such as the widening of the power lines, the reduction in the aperture ratio caused by the widening of the upper and the lower capacitor electrodes and the short circuit between the upper and the lower electrodes caused by the roughness of the flattening layers. Two kinds of the OLEDs are provided. One is an OLED comprising a region of LE layer sandwiched between the upper and lower electrodes is formed on a power line of TFT for driving the pixel. Another comprises a region of the LE layer formed on an electrode of capacitor connected to the TFTs to control the light-emitting element. Accordingly, without forming a flattening layer on the light-emitting layer, there is no electric short circuit between the lower electrode and the upper electrode.

A lenticular lens has a light transmitting substrate and a plurality of lens elements formed on the light transmitting substrate. The lens elements are defined in such a way that ridges thereof are aligned in parallel with each other, wherein 30°≦θ 10% ≦100° and R≦20%, where θ 10% is a diffusing angle range with respect to normal of the one surface in the case that when light is entered from the opposite surface and transmitted from the one surface, the intensity of the light transmitted is equal to or more than 10% of the intensity of the light transmitted in a peak direction of a main lobe; and R is the ratio of side lobes to main lobe. The intensity of side lobes which causes light loss and light stray can be remarkably reduced. Light can be equally and isotropically focused on in a predetermined diffusing angle range.

For producing an abrasive tape (11) including a film substrate (2) and a polishing abrasive layer (10) laminated on one surface of the film substrate (2) and having on the outer surface thereof a plurality of recessed parts (9), the film substrate (2) is wrapped partially around the outer peripheral surface of a roll formplate (1) having on the surface thereof a plurality of concavities (5), and, as the roll formplate (1) is rotated, the film substrate (2) is fed thereto. On one hand, an ionizing radiation curing type resin (3) is supplied into the interface between the roll formplate (1) and the film substrate (2) therearound to be formed by the concavities (5), and the recessed parts (9) are formed on the resin surface. During this forming, radiation rays (R) are projected from an ionizing radiation ray source (8) toward the resin (3) thereby to cure the resin (3) and, at the same time, to render the resin (3) and the film substrate (2) into an integral structure. The abrasive tape (11) obtained in this manner is separated from the roll formplate (1). The abrasive tape (11) thus obtained is of high product quality. The production method is highly efficient and is suitable for mass production of abrasive tapes of identical concave-convex surface figuration.

In order to manufacture a grinding tape (11) which consists of a film substrate (2) and a grinding layer (10) laminated on one surface thereof, and which has a plurality of recesses (9) in the surface of the grinding layer (10), a film substrate (2) is wound partially around the circumferential surface of a roll intaglio (1) provided with a plurality of recesses (5) in the surface thereof, and the film substrate (2) is fed as the roll intaglio (1) is rotated. In the meantime, an ionizing radiation setting resin (3) is fed between the roll intaglio (1) and the film substrate (2) passed therearound, in such a manner that the resin (3) is shaped by the recesses (5) to cause recesses (9) to be formed in the surface of the resin (3). During the shaping of the resin (3), the radiation R is applied from an ionizing radiation source (8) to the resin (3) so as to harden the resin (3) and combine the resin (3) and film substrate (2) with each other unitarily. A grinding tape (11) thus obtained is peeled off from the roll intaglio (1). This grinding tape (11) is of a high quality. The method of manufacturing such grinding tapes has a high efficiency, and is suitable for the mass-production of grinding tapes having the same recesses and projections on the surfaces thereof.
