Abstract
Signals of odd lines in progressive scanning image signals in a first frame are extracted and displayed along odd lines on a matrix-type display device such as a liquid crystal display panel. Further, signals of even lines in progressive scanning image signals in a second frame successive to the first frame are extracted and displayed along even lines on the display device. Thus, one image of a frame is displayed on the display device in two frame periods so that one of the first and second steps is performed after the other thereof is performed. Alternatively, one of the signals of odd lines are displayed along two successive odd and even lines, while one of the signals of even lines are displayed along two successive even and odd lines. The display methods can be applied to a display panel having a larger number of scanning lines than a number of signal lines. Light leakage in a liquid crystal panel including polymer dispersion liquid crystal due to lateral electric field near pixel electrodes is prevented by providing light-shielding films on the pixel electrodes. Light leakage is also prevented by providing a polarizer above one of the two sides of the panel.
