Abstract

An electro-optical device includes: data lines extending in a first direction above a substrate; scanning lines extending in a second direction and intersecting the data lines; pixel electrodes and thin-film transistors arrayed so as to correspond to intersection regions of the data lines and the scanning lines; capacitors formed at a layer higher than the semiconductor layer of the thin-film transistors and at a layer lower than the pixel electrodes, and electrically connected to pixel potential; and upper light shielding film positioned between the data lines and the pixel electrodes; the upper light shielding film defining at least the corners of pixel opening regions; and the scanning lines, the data lines, and the capacitors, being formed in the light shielded region.

Description

technical field [0001] The present invention relates to the technical field of electro-optical devices such as liquid crystal devices and electronic equipment. In addition, the present invention also relates to technical fields such as electrophoretic devices such as electronic paper, EL (Electroluminescence) devices, and devices using electron emission elements (Field Emission Display and Surface-Conduction Electron-Emitter Display). Background technique [0002] Conventionally, electro-optical devices such as liquid crystal devices are known in which an electro-optic material such as liquid crystal is interposed between a pair of substrates, and light is transmitted through the substrates so as to display images. The "display of an image" here is realized by, for example, changing the state of the electro-optic material for each pixel to change the transmittance of light so that light with different gradations can be recognized for each pixel. [0003] As such an electro-...
