Abstract
A display device includes a light emitting element layer, and an optical pattern layer disposed on the light emitting element layer. The optical pattern layer includes a first pattern layer having a base part and protruding parts, and a second pattern layer having a refractive index less than a refractive index of the first pattern layer to scatter light incident to the optical pattern layer and minimize reduction in front efficiency, thereby providing an improved display quality of a side viewing angle.
