Abstract

A display device comprises: a thin film transistor substrate; a counter substrate disposed to be opposed to the thin film transistor substrate; and a plurality of spacers protruding from the counter substrate toward the thin film transistor substrate, wherein the counter substrate includes: a black matrix including a first opening and a second opening that are adjacent to each other in a first direction; a first color filter being disposed while overlapping with the first opening and the second opening in planar view; and a second color filter being disposed while overlapping with at least a part of a region between the first opening and the second opening in planar view, and a first spacer included in the plurality of spacers overlaps with the second color filter between the first opening and the second opening in planar view.
