Abstract: A plurality of display elements each includes two signal lines: S1 and S2. An electrode 4, which is one of the electrodes constituting an element capacitor Cp, is connected to the signal line S1 via a switching element TFT1, while the other electrode 5 is connected to the signal line S2 via a switching element S2. The gate electrodes of the switching elements TFT1 and TFT2 are connected to a single common scanning line G. With this structure the drive voltage applied to the element capacitor can be increased even when a TFT has a limited withstand pressure.

Abstract: A source driver outputs a data signal and a reset (black) signal alternately to a source line. Four-hundred and eighty gate lines are divided into three groups each comprising 160 lines, and connected to gate drivers. A display control section outputs a discriminant signal, a scan start signal and a clock signal to the gate drivers, where the nth gate line is selected with the data signal outputted by the source driver, and where the (n+160)th gate line is selected with the reset signal outputted. Further, n is shifted sequentially. By writing the reset signal during the latter ? of one frame like this, light leakage of pixels that are changed over from white display to black display is eliminated. Also, blurs of edge portions of a motion picture are reduced. Thus, display grade for motion pictures is enhanced with a minimum improvement.

Abstract: A liquid crystal display apparatus provided with liquid crystal compensation plates and ?/4 plates on both sides of a liquid crystal cell, in a sequence that the liquid crystal compensation plates, then the ?/4 plates. Further provided is Rth compensation film between the ?/4 plate and linear polarization film. Set substantially at zero is a retardation Rth1 in a perpendicular direction in a range from the linear polarization films to the ?/4 plates, excluding the ?/4 plates. This gives a retardation (in a perpendicular direction) for optically compensating the liquid crystal cell a closer position to the liquid crystal cell. As a result, a broad angle of visibility can be maintained, without losing a balance between viewing angle characteristics from the above position (or the bottom position) and those from the right position (or the left position), while it is possible to prevent contrast ratio in a front direction from being lowered. Therefore, an LCD having good display quality can be realized.

Abstract: Data, such as video signal data, for example, for a next desired frame is first modulated or varied to facilitate a transition from a current frame to a next desired frame. A modulation processing section can be used, for example, to thus produce a corrected video signal to facilitate the current-to-next desired grayscale level transition. Thereafter, spatial filtering is then carried on the corrected video signal, using a spatial filtering section for example. As such, high frequency components in a spatial domain may be reduced, even after the spatial frequencies of an ordinary video signal and potentially those of noise have been scaled up. Therefore, undesirable noise-caused display quality degradation can be reduced or even prevented, while pixel response speed as a result of the facilitation of grayscale level transition, is increased.

Abstract: A pixel 3 includes a pixel electrode 31 and opposed electrodes 32 for generating electric fields between a pair of substrates in directions substantially parallel to the substrates and also includes two regions S1 and S2 defined by the pixel electrode 31 and the opposed electrodes 32. The electric fields are generated in the adjacent regions S1 and S2 in opposite directions. A liquid crystal layer has a structure in which a slow axis indicating a refractive-index anisotropy as viewed in a direction normal to the substrates is vertical to the electric-field direction without an application of an electric field whereas slow axis in these regions S1 and S2 rotate about axes normal to the substrates in opposite directions. In this manner, the viewing angle of a liquid crystal display device is increased and coloring is prevented. In addition, the response speed and the aperture ratio are enhanced.

Abstract: While image data is written into either one of first, second, third frame memories 1, 2 and 3, image data are repetitively read two times from the remaining two memories in one vertical synchronization interval and transferred to an arithmetic unit 4, and this operation is executed with the frame memories changed sequentially. An arithmetic unit 4 refers to a look-up table on the basis of two inputted data values and, when the data value of the current image signal is greater than the data value of the previous image signal, the unit 4 transfers image data of a value greater than the data value of the current image signal to a liquid crystal display device 5. Thus, the step response characteristic is improved for the improvement of the dynamic image display quality.
