Abstract

A liquid crystal display device includes plural reflective electrodes supplied with a video signal, second light-blocking conductive films below the reflective electrodes with a first insulating layer therebetween, and a first light-blocking film below the second light-blocking conductive films so as to cover spacing between the second light-blocking conductive films. Each of the second light-blocking films is electrically connected to a corresponding one of the reflective electrodes, and is disposed to cover at least a portion of spacings between the corresponding one of the reflective electrodes and ones of the reflective electrodes adjacent thereto. A second insulating layer is interposed between the first and second light-blocking films, and its thickness is from 150 nm to 450 nm.
