Abstract
A reflective LCD has first and second light blocking metal films that are formed one upon another between a semiconductor substrate and reflective pixel electrodes with an insulating film being laid on and under each of the light blocking metal films, to block part of read light, which has been made incident from a transparent substrate side to liquid crystals through a counter electrode and has penetrated a third interlayer insulating film through openings formed between adjacent ones of the reflective pixel electrodes, from reaching switching elements. One of the first and second light blocking metal films covers the openings formed between adjacent ones of the reflective pixel electrodes. The first and second light blocking metal films in each pixel are electrically connected, through third via holes, to a corresponding switching element, reflective pixel electrode, and storage capacitor.
