Abstract:
1. A liquid crystal display device, comprising: a pair of substrates disposed to be opposite to each other; a pixel electrode formed on one of said substrates; an opposite electrode formed on the other of said substrates; an alignment film formed on said opposite electrode; a protrusion formed between said opposite electrode and said alignment film; spherical spacers scattered between the pair of substrates; a liquid crystal sealed between the pair of substrates; and an alignment film protrusion as an alignment regulating structure formed by said alignment film in an area corresponding to said protrusion, such that said protrusion causes said alignment film protrusion to protrude toward said liquid crystal, said alignment film protrusion being formed to be recessed on a side opposite to the one of the pair of substrates and for regulating an alignment direction of the liquid crystal contacting said alignment film protrusion, said alignment film protrusion including a recessed portion, formed within an outer surface thereof, within which at least one of said spherical spacers is seated, whereby said recessed portion reduces compressive stress exerted on said substrates by said spherical spacer seated therein; wherein said spherical spacers are scattered in an area opposite said pixel electrode, and wherein said spherical spacers are scattered in an area with no alignment film protrusions.
