Display device comprising a recessed portion that is formed with at least one convex portion at a bottom of the recessed portion and wherein the recessed portion faces a columnar spacer
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.
