Abstract
The invention provides a liquid crystal panel substrate having transistors and reflectors connected to the transistors on a substrate to allow bright reflection display of high quality at wide viewing angles by providing the most suitable reflection characteristics to the reflectors. Under the reflectors, first conductive layers are overlaid in regions corresponding to the reflectors and formed in a concave-convex condition by forming a large number of openings. Also, in a plan view, a light-shielding film covering gaps between the reflectors is formed of the second conductive layer, and may have no openings.
