Abstract
The invention provides an electro-optic device capable of keeping the cell gap constant or substantially constant throughout the substrate surface regardless of the existence of a liquid crystal inlet. The electro-optic device of the invention has a TFT array substrate and an opposite substrate formed to sandwich an electro-optic material; a liquid crystal inlet to communicate the clearance sandwiched between the substrates with the exterior; and a plurality of columnar spacers scattered within the surfaces in parallel to the substrates to keep the clearance between the substrates at a predetermined thickness, the columnar spacers being disposed more densely in the vicinity of the liquid crystal inlet and more sparsely in the other area within the surfaces.

An electro-optic device, comprising:
- an electro-optic material;
- a pair of substrates sandwiching the electro-optic material;
- an inlet to communicate a clearance sandwiched between the pair of substrates with an exterior thereof;
- a plurality of columnar spacers scattered within surfaces of the pair of substrates facing each other, the columnar spacers being disposed more densely in a vicinity of the inlet and more sparsely beyond the vicinity of the inlet within the surfaces.
