1. An electro-optical device, comprising:
- an electro-optical substance;
a pair of substrates holding the electro-optical substance; and
pole-like spacers provided on at least one substrate of the pair of substrates, on a to-be-provided surface of the at least one substrate facing the electro-optical substance, each pole-like spacer having an elongated sectional shape including a rounded head end portion and rear end portion in a direction of elongation, and at roots thereof, a slope portion with a surface connecting to the to-be-provided surface of the at least one substrate.

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.

10. An electro-optical device, comprising:
-
an electro-optical substance; a pair of substrates holding the electro-optical substance; pole-like spacers provided on at least one substrate of the pair of substrates, on a to-be-provided surface of the at least one substrate facing the electro-optical substance, each pole-like spacer having an elliptic-shaped cross-section including a rounded head end portion and rear end portion in a direction of a major axis of the elliptic-shaped cross-section, and at roots thereof, a slope portion with a surface connecting to the to-be-provided surface of the at least one substrate; and an orientation film formed on the to-be-provided surface of the at least one substrate, the orientation film being rubbed in the direction of the major axis of the elliptic-shaped cross-section.

11. An electro-optical device comprising:
-
a TFT array substrate; a counter substrate; pixel electrodes formed on the TFT array substrate; a counter electrode formed on the counter substrate; an electro-optical substance held between the TFT array substrate and the counter substrate; and a light-shielding film formed between the counter substrate and the counter electrode, the light-shielding film including pole-like spacers arranged along gaps among the pixel electrodes.
