Abstract:
A liquid crystal display device of a transflective type of the present invention is so arranged that a transparent electrode and a reflective electrode that compose a pixel do not match in position with each other, and the reflective electrode straddles a gate bus line and a source bus line. With this, a transparent electrode and a reflective electrode that are adjacent to each other without being electrically connected are arranged so as to overlap with each other, when viewed in the normal direction of the display surface, thereby eliminating an inter-pixel region therebetween. This reduces a ratio of the inter-pixel region with respect to the display screen, so that it is possible to further improve a pixel aperture ratio and to improve light utilization efficiency.
