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

摘要

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.

1. A display device comprising:
a first substrate having an organic film and an alignment film; 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; wherein the recessed portion is formed with at least one convex portion at a bottom of the recessed portion, and a height of a top of the at least one convex portion from the first substrate is lower than a height of an upper surface of the organic film from the first substrate; wherein a thickness of an alignment film on the at least one convex portion is smaller than a thickness of the bottom of the recessed portion; wherein a top of the columnar spacer is in contact with the at least one convex portion formed on the recessed portion; and wherein an area at the bottom of the recessed portion is larger than an area at the top of the columnar spacer.
