Abstract:
A liquid crystal display device including two substrates, with a pixel electrode formed on one substrate and an opposite electrode formed on the other substrate. The device also includes an alignment film formed on the opposite electrode, a protrusion formed between the opposite electrode and the alignment film, spherical spacers, liquid crystal, and an alignment film protrusion formed by the alignment film in an area corresponding to the protrusion, such that the protrusion causes the alignment film protrusion to protrude toward the liquid crystal. The alignment film protrusion is recessed on a side opposite one of the substrates and regulates an alignment direction of the liquid crystal contacting it. Further, the alignment film protrusion includes a recessed portion, within an outer surface thereof, within which at least one spherical spacer is seated, whereby the recessed portion reduces compressive stress exerted on the substrates by the spherical spacer seated therein.
