Abstract

An electro-optical device includes, above a substrate: a data line extending in a first direction; a scanning line extending in a second direction and intersecting the data line; pixel electrode and thin film transistor disposed so as to correspond to intersection regions of the data line and the scanning line; a storage capacitor electrically connected to the thin film transistor and the pixel electrode; a shielding layer disposed between the data line and the pixel electrode; an interlayer insulating film disposed as the base of the pixel electrode; and a contact hole formed in the interlayer insulating film, to electrically connect the thin film transistor to the pixel electrode. Further, the entire region inside the contact hole is filled with a filler.

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, and devices using EL (Electroluminescence) or 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 sandwiched between a pair of substrates, and light is transmitted through them so as to display an image. 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-optical device...
