PROBLEM TO BE SOLVED: To yield a laminate which comprises first and second silicone layers different from each other in hardness and is excellent in integrity and adhesion between the silicone layers. SOLUTION: A first silicone layer having a JIS A hardness lower than 50 is formed by curing a first addition-curing-type organopolysiloxane composition containing a first adhesion promotor. On the first silicone layer, a second addition-curing-type organopolysiloxane composition containing a second adhesion promotor is applied and cured to form a second silicone layer having a JIS A hardness of 50 or higher.

An organic EL element section ( 1000 ) is formed on a circuit formation section ( 102 ) formed on a circuit board ( 101 ). The organic EL element section ( 1000 ) is covered with a protective layer ( 113 ) including an SiN x O y film. The SiN x O y film has infrared absorption characteristics including: an Si—O—Si stretching vibration absorption peak appearing at energy lower than 1,000 cm −1 ; an absorption intensity of an Si—N stretching vibration absorption peak appearing in the vicinity of around 870 cm −1 which is 0.75 or more times an absorption intensity of the Si—O—Si stretching vibration absorption peak; and an absorption peak intensity in a range of 2,000 to 4,000 cm −1 , which is 5% or less of the absorption intensity of the Si—N stretching vibration absorption peak. Thus, the protective film having an excellent moisture-blocking property may be obtained, and life property of an organic EL display device may be improved.

PURPOSE:To provide a device for aligning a light source capable of accurately and easily realizing alignment and capable of coping with any light condensing unit by successively arranging a pinhole plate where at least one hole is formed and an optical system projecting to the pinhole plate on a light beam outgoing side of the optical system. CONSTITUTION:In the case of aligning a metal halide lamp with a parabolic mirror, the metal halide lamp being the light source 1 is temporarily fixed on a jig which can be adjusted in directions X, Y, Z and theta with respect to the parabolic mirror used as the light condensing unit 2. Then, the pinhole plate 3 where at least one hole is formed, a projection lens 4 and a screen 5 are successively arranged in front of an illuminating system consisting of the light source 1 and the unit 2. This device is constituted so that the light source is aligned with the light condensing unit by using a defocused image caused by defocusing the projected image on the pinhole plate. By the device, the alignment is accurately and easily realized and the device can cope with any light condensing unit.

PURPOSE:To provide a projection type image display device which can provide illuminating light having good parallelism and a uniform illuminance distribution and can provide a uniform, bright screen of high picture quality while reducing the ununiformity of contrasts due to photoelasticity and restraining generation of color unevenness CONSTITUTION:The form of a correcting lens 3 is designed following the Snell's law so that of rays of light reflected by a reflecting mirror 2 those which are not parallel to the optical axis 9 of a lighting system are refracted and made parallel to the optical axis 9 Illuminating light from the lighting system is therefore good at parallelism Even when the relative positions of a light source 1 and the reflecting mirror 2 are adjusted so that the illuminating light is not extracted, the rays of light whose parallelism is made worse by deviating of the positions are made parallel by the correcting lens 3, so that the ununiformity of the illuminance of the illuminating light is improved without deteriorating the parallelism

CONSTITUTION:Moire fringes are formed on a screen 19 by making light, which is made incident on the work 40 composed of a liquid crystal display element and a microlens array, parallel, convergent, or divergent through a field lens 16. While the moire fringes are observed, one work 40 is moved to the other to predetermine and match the moire fringes with a specific position on the screen 40, so that the work 40 can be positioned. The size of the picture elements of the liquid crystal display element is determined once the moire fringes are positioned, and then a photosetting adhesive supplied to between the works 4 is set with light to complete the sticking of the works 40.
