ABSTRACT:
The invention provides an electro-optical device which displays image of high quality without forming poorly oriented regions that stem from the presence of pole-like spacers, yet achieving a high numerical aperture. Pole-like spacers according to the invention are provided on at least either one of a first substrate and a second substrate holding a liquid crystal layer and on the to-be-provided surface of the one substrate on the side facing the liquid crystal layer, the pole-like spacers having, at the roots thereof, a slope portion with a surface smoothly connecting to the to-be-provided surface.
