Abstract:
1. A method of manufacturing an electro-optical device, that has a matrix of pixels, a peripheral area surrounding the matrix of pixels, data lines, scanning lines, driving elements formed to correspond to intersections of the data lines and the scanning lines for individual pixels of the matrix of pixels, and pixel electrodes provided to correspond to the driving elements, the method of manufacturing an electro-optical device comprising: forming a lower light-shielding film in the peripheral area surrounding the matrix of pixels; forming a base insulation layer over the light-shielding film; forming an etching stopping layer over the base insulation layer, the etching stopping layer being formed from a semiconductor layer; forming driving elements; forming a common line above the etching stopping layer, the common line short-circuiting the scanning lines; forming a first interlayer insulating film over the scanning lines and the driving elements; forming contact holes through the first interlayer insulating film to the driving elements; forming data lines electrically connected to the driving elements through the contact holes; and forming a cutting hole in the first interlayer insulating film by etching so as to cut the common line without passing through the lower light-shielding film.
