Abstract: 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.

Abstract: A display device includes a first substrate having organic and alignment films, a second substrate adhered to the first substrate by a sealant which surrounds a pixel region, a columnar spacer formed on the second substrate defining a distance between the first substrate and the second substrate, and a recessed portion formed in the organic film of the pixel region, the recessed portion facing to the columnar spacer. The recessed portion has a convex portion at a bottom of the recessed portion, and a height of a top of the convex portion from the first substrate is lower than a height of an upper surface of the organic film from the first substrate. A thickness of an alignment film on the convex portion is smaller than a thickness of the bottom of the recessed portion, and a top of the columnar spacer is in contact with the convex portion.
