Matrix substrate, liquid crystal display device and projection type liquid crystal display apparatus employing the same with reduced field-through effect between subsequent scan lines

摘要

A novel active matrix type liquid crystal display device is provided for displaying an image by scanning two-dimensional liquid crystal panel with a vertical shift register and a horizontal shift register. The liquid crystal display device has an array of pixel switches for turning on and off liquid crystal pixels and pixel electrodes for applying voltages to the liquid crystal pixels, wherein the gate of the pixel switch turns on plural lines of the liquid crystal pixels simultaneously for a prescribed time period, wherein the plural lines of the pixels are turned on at the same time, and the timing of the change from the turned-on state to a turned-off state is different for the respective lines. With this structure, the number of the transistors constituting the shift register is reduced, and the field-through between the adjacent pixels is decreased, which enables high integration and high fineness of the image display.
