摘要： Projecting sections controlling alignment directions of liquid crystal molecules are provided on at least one of an active matrix substrate and a counter substrate. When viewed from a direction perpendicular to a surface of the active matrix substrate or of the counter substrate, an outline shape of the projecting sections is constituted by continuously arranging a plurality of unit patterns each having a side in parallel with the polarization axis of the first polarizing plate and a side in parallel with the polarization axis of the second polarizing plate. This makes it possible to provide a liquid crystal panel that performs better display with high contrast by reducing a light leakage during a black display period and by ensuring a light transmittance during a gray level display period and a white display period.

摘要： In a wiring figure pattern of a display panel, each wiring is separated into bands of optimal widths by slits of a constant width as a wiring figure pattern so that minimum light irradiation for curing a photocuring sealing material can be carried out without increasing the electric resistance of the wiring. The optimal width means a resistance such that light coming from both sides of the band cures the sealing material on the upper surface of the band without influencing the driving and display of liquid crystal. At a point where the width of wiring becomes two times or more of the optical width between the start point and end point of intersection of the wiring and the sealing material region, the wiring is divided by the slit. A first branch forms the band of the optimal width extending from the branch point to the end point, whereas the second branch extends to the end point and is spaced apart from the first branch by the width of the slit. At a point where the width becomes two times or more of the optimal width, the wiring is divided. Subsequently, branching is repeated until the end point is reached. A continuous triangle is formed in the slit at each branch, thus adjusting the width of the bands to have the optimal width.

摘要： In one embodiment of the present invention, a liquid crystal display device is disclosed in which a gate driver applies a gate-on pulse so that a second period is longer than a first period. The first period and the second period are defined as follows. Among gate-on pulses applied before the moment of polarity inversion of a data signal, the last end of the gate-on pulse nearest to the moment of the polarity inversion is earlier than the end time of the horizontal period during which the gate-on pulse is applied. The first period starts at the last end of the gate-on pulse and ends at the end time of the horizontal period during which the gate-on pulse is applied. The second period starts at the moment of the polarity inversion and ends at the moment of the application start of the gate-on pulse nearest to the moment of the polarity inversion among the gate-on pulses applied after the polarity inversion. Thus, even when a data signal waveform is not sharp upon polarity inversion, it is possible to suppress display unevenness and perform a high-quality display.

摘要： A semiconductor device accurately monitoring temperature of a semiconductor chip even in a noisy environment, while not requiring a highly accurate detection circuit. A PTC element is bonded onto an IGBT chip. Then, a constant current flows from a constant current source through the PTC element, and an output voltage of the PTC element is detected by a voltage monitor. When output voltage increases, a voltage applied to a gate electrode by a detection circuit is decreased. Since the PTC element is directly arranged on the IGBT chip, the temperature of the IGBT chip can be monitored with high accuracy. Further, since the change in output voltage of the PTC element per 1° C. is large, a highly accurate detection circuit is not necessary, thereby allowing accurate monitoring of the temperature of the IGBT chip even in a noisy environment.
