Patent ID: 7075109

Claim:
An electro-optical device comprising: an electro-optic material sandwiched between a pair of substrates; a plurality of pixel electrodes that are arranged with gaps therebetween in plan view above one of the substrates; an underlying layer that underlies the pixel electrodes; at least one of wires and electronic elements which are formed below the underlying layer and which are electrically connected to the pixel electrodes; a protection insulating film that is formed on at least part of the underlying layer in the gaps and that is formed on edge portions of the pixel electrodes so as to cover end surfaces of the edge portions of the pixel electrodes; an alignment layer that is provided on the protection insulating film and the pixel electrodes; and edge portions of the protecting insulating film having, at edges of the edge portions, tapered portions with a taper angle of 45Â° or less.
