Abstract
A display device includes: a substrate; a bank layer on the substrate, and defining a light-emitting area; an organic light-emitting layer in the light-emitting area; a thin-film sealing layer covering the organic light-emitting layer and the bank layer; an inorganic layer including a base part on the thin-film sealing layer, and a protruding pattern part protruding from the base part in a thickness direction and including a lateral surface having a reverse taper angle; a first low refractive organic layer on the base part of the inorganic layer; and a high refractive organic layer covering the first low refractive organic layer and the inorganic layer. A lateral surface of the first low refractive organic layer contacts the lateral surface of the protruding pattern part, and an upper surface of the first low refractive organic layer protrudes more than an upper surface of the protruding pattern part in the thickness direction.
