Abstract
A display device includes a lower substrate and an upper substrate opposite the lower substrate; a lower electrode on the lower substrate; a bank insulating layer on the lower substrate, the bank insulating layer covering an edge of the lower electrode; a light-emitting layer on a surface of the lower electrode exposed by the bank insulating layer; an upper electrode on the light-emitting layer; a reflective pattern on the upper substrate, the reflective pattern overlapping with the bank insulating layer; and a half-mirror layer on a surface of the upper substrate exposed by the reflective pattern.
