Document Type and Number:
Japanese Patent JP3810788
Kind Code:
B2
Abstract:
In a display device of the invention, driving of the piezoelectric element is controlled to change the light path of the propagating light inside a light guiding plate. By illuminating a liquid crystal panel in this manner, an illumination time and a no illumination time can be provided for the liquid crystal panel within one frame period. This realizes impulse-type-like display in displaying moving images on the liquid crystal panel, and thereby improves an image quality of moving images. Further, since the light is used only in desired regions, spontaneous luminance can be improved and the light can be used more efficiently.
