Liquid crystal display device wherein an alignment film over a concave portion has a thickness which is thicker than a thickness of the alignment film over convex portions

摘要

A display device includes a first substrate, a second substrate and liquid crystals therebetween, the first substrate having a flat portion, an alignment film, and a concavo-convex pedestal formed in a pixel region, wherein the concavo-convex pedestal having at least two convex portions and recessed portions, and the at least two convex portions of the concavo-convex pedestal are at a position lower than a position of the flat portion. A thickness of the alignment film on the convex portions is less than a thickness of the alignment film on the recessed portions, and a second substrate has a columnar spacer which contacts the at least two convex portions of the concavo-convex pedestal.
