Electro-optical device and electronic apparatus
View Patent ↗The invention provides an electro-optical device having a light-shielding layer for preventing light from entering semiconductor elements. In particular, a liquid crystal display device of the present invention includes an electro-optical material between an element substrate having pixel electrodes and an opposing substrate facing the element substrate. The element substrate includes semiconductor elements for driving the pixel electrodes, insulation films covering the semiconductor element, and a reflective plate disposed on the insulation films, the reflective plate having openings. The semiconductor elements adjacent to the element substrate includes a light-shielding layer for shielding the semiconductor element from incident light, the light-shielding layer having openings in substantially the same regions as the openings in the reflective plate.
1. An electro-optical device, comprising:
an electro-optical material disposed between an element substrate having pixel electrodes and an opposing substrate facing the element substrate,
the element substrate including semiconductor elements that drive the pixel electrodes, insulation films covering the semiconductor elements, and a reflective plate disposed on the insulation films, the reflective plate having openings,
each of the semiconductor elements adjacent to the element substrate having a light-shielding layer disposed on another insulation film, the another insulation film formed on the element substrate, the light-shielding layer shielding the semiconductor element from incident light, the light-shielding layer formed substantially over entire reflective display regions of the device and having openings only in substantially the same regions as those of the openings in the reflective plate.
2. The electro-optical device according to claim 1 , each of the semiconductor elements being coupled with a source line and a gate line, the source line being covered by one of the pixel electrodes to avoid contact with one of the openings of the light-shielding layer.
3. An electronic apparatus comprising the electro-optical device according to claim 1 .
