摘要： An active matrix substrate capable of suppressing a change in an off characteristic of the TFT even when current passage time becomes longer is provided. A diode is connected between a video signal line and a conductive plate formed so as to cover a TFT of a pixel formation portion. Current is passed to the diode when a potential of a video signal applied to the video signal line is lower than that of the conductive plate, and the potential of the conductive plate becomes equal to that of the video signal line. No current flows when the potential of the video signal is higher than that of the conductive plate and the potential of the diode remains the same. Consequently, a leak current which flows from the pixel electrode of the pixel formation portion to the video signal line when the TFT is in the off state is suppressed.

摘要： A color display pixel PCD in a liquid crystal display device (100) includes first through fourth pixels P1 through P4 arrayed in two rows by two columns, and first and second signal lines (13a, 13b) which are located in correspondence with each column of pixels and are supplied with signal voltages of polarities opposite to each other from a signal line driving circuit (30) in each vertical scanning period. A TFT (14) of one of the first and third pixel P1 and P3 is connected to the first signal line (13a), and a TFT (14) of the other pixel is connected to the second signal line (13b). A TFT (14) of one of the second and fourth pixel P2 and P4 is connected to the first signal line (13a), and a TFT (14) of the other pixel is connected to the second signal line (13b). The TFTs (14) of the first through fourth pixels P1 through P4 are controlled to be ON/OFF by a common scanning signal, and the polarities of the signal voltages supplied to the first and second signal lines (13a, 13b) are constant during an arbitrary vertical scanning period. Owing to this, the load on the signal line driving circuit is reduced.

摘要： A diode (130) whose anode is connected to a conductive plate (140) formed so as to cover a TFT (120) of a pixel formation portion (110) and whose cathode is connected to a video signal line is provided. With the configuration, when potential of a video signal applied to the video signal line is lower than that of the conductive plate (140), a current is passed to the diode (130), and the potential of the conductive plate (140) becomes equal to that of the video signal line. On the other hand, when the potential of the video signal is higher than that of the conductive plate (140), no current flows, so that the potential of the diode (130) is held as it is. As a result, the potential of the conductive plate (140) is clamped to the lowest potential among potentials of video signals.Consequently, a leak current which flows from the pixel electrode Ep of the pixel formation portion (110) to the video signal line when the TFT (120) is in the off state is suppressed. Thus, the present invention provides an active matrix substrate capable of suppressing a change in an off characteristic of the TFT even when current passage time becomes longer.

摘要： A liquid crystal display of the present invention contains a first panel and a second panel being stacked. Adjacent pairs of polarizers (A to C) disposed on the panels form crossed Nicols. When the first panel produces a display according to a first display signal, the second panel produces a display according to a second display signal obtained from the first display signal. Each of the two joined panels is provided with a light diffusion layer having a light diffusing property. The provision of the light diffusion layers enables reducing moire pattern occurrences which would otherwise markedly increase when two liquid crystal panels are stacked. As a result, the liquid crystal display has high display quality.

摘要： The method of driving a liquid crystal display in accordance with one embodiment of the present invention is a method of driving a liquid crystal display whereby a first liquid crystal panels produces a display from a first display signal and the second liquid crystal panel produces a display a second display signal derived from the first display signal, the first and second liquid crystal panels being stacked on top of each other. The luminance of the first liquid crystal panel is extended based on the luminance extension ratio obtained from the gray levels for dots contained in the first display signal and a logical maximum gray level of input image data. The luminance of the second liquid crystal panel which produces a display from the second display signal is lowered by the amount by which luminance is extended on the first liquid crystal panel. A liquid crystal display with high display quality is realized by restraining decrease in saturation which would otherwise become obtrusive when two liquid crystal panels are stacked.

摘要： The method for producing a metallic wiring board of this invention comprises the steps of: implanting nitrogen on a surface of a substrate; forming a metallic film including, as a main component, one of Ta and Nb on the surface of the substrate where nitrogen is implanted by a sputtering method to form a metallic wiring by patterning the metallic film; and forming an insulating film by anodic oxidation of a surface of the metallic wiring. In the step of forming a metallic wiring form Ta or Nb on a substrate or a protective layer including nitrogen to anodic-oxidize the surface of the metallic wiring, Ta ions or Nb ions do not enter the substrate. Further, the substrate or a protective layer is doped with nitrogen, and a Ta layer is formed by the sputtering method thereon. The sputtering method has a characteristic that a material contained in the substrate is mixed into a film formed in the initial stage of the coating. Therefore, the doped nitrogen enters the Ta film, and a thin .alpha.-Ta layer is formed on the substrate or the protective film. The Ta layer to be epitaxially grown thereon is an .alpha.-Ta layer including no impurity. Thus, a Ta layer with a specific resistance of about 25 .mu..OMEGA.cm is obtained.
