The present invention provides a liquid-crystal display panel with which it is possible to alleviate an occurrence of display misalignment and a degradation of contrast when using a color filter of four or more colors. This liquid-crystal display panel comprises a color filter substrate further comprising four or more color layers and a shutter layer, wherein a repeating unit of the four or more color layers is treated as one pixel. The four or more color layers respectively overrun a portion of the shutter layer. The liquid-crystal display panel includes regions wherein color layers of the same color which are included in different pixels, respectively, are arranged in either the same rows or the same columns. Of the four or more color layers which configure the one pixel, the overrun width with respect to the shutter layer whereon a color layer with a color with greater brightness is positioned between the color layers of the same color is narrower than the overrun width with respect to the shutter layer whereon a color layer of a color with lesser brightness is positioned between the color layers of the same color.

The reflection-polarization member is disposed on the base substrate to reflect and polarize incident light. The first electrode is disposed in a unit pixel area of the reflection-polarization member. The insulation layer is disposed on the first electrode. The pixel wall is disposed on the insulation layer and defines the unit pixel area. Therefore, the entire area of a unit pixel may be used as a reflective area or a transmissive area, and thus an aperture ratio may be improved in a reflection mode or a transmission mode.

Display substrate, method of manufacturing the same and electrowetting display panel having the display substrate

Wafer level transient voltage measurement (WLTVM) to estimate the short circuit capability of AlGaN/GaN HEMT devices is suggested. Two groups of samples with similar DC and switching properties but different short circuit capabilities of 4-7 and $>{10}\mu \text{s}$ were evaluated. The extracted junction temperature and the measured saturation/linear current under repeated short circuit stresses suggest that the short circuit failure is attributed to the degradation in the drift region. The WLTVM could measure the transient potential change along the drift region during short circuit condition. The sample with lower short-circuit survivability showed a faster propagation of the high field traveling from the gate to the drain. The time the high electric field reaches the drain coincides with the time of the short circuit failure. In addition to providing the insight into the short circuit failure mechanism, wafer-level method can provide a quick and non-destructive evaluation of the short circuit capability before packaging devices.

Estimation of Short Circuit Capability of GaN HEMTs Using Transient Measurement

This work reports the transient measurement of the AlGaN/GaN high electron-mobility transistor (HEMT) drift region potential in the high power state during switching. The effect of high power stress has been reported by device characterization after stress or during high power DC stress at voltages below the operating voltages to avoid device failure. However, transient measurement during high power stress is challenging, since the device can sustain the high power stress only for a few $\mu \text{s}$ before failure occurs. In this work, a test structure with voltage probe inserted in the drift region between the gate and the drain is used to perform real-time measurement of the drift region potential during the high power state at operating voltages. It is found that the high electric field formed at the gate side during the off-state stress propagates towards the drain side within a few $\mu \text{s}$ . The propagation speed of this high electric field increased with increase in drain voltage. It is proposed that trapping of hot channel electrons is causing this effect, and dynamic on-resistance measurement suggests that the traps are 0.44 eV below the conduction band.
