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.

Abstract: A liquid crystal display may be manufactured by forming a first alignment layer on a first base substrate, forming a second alignment layer on a second base substrate, disposing liquid crystal on the first alignment layer or the second alignment layer, and combining the first base substrate and the second base substrate with each other. At least one of the first and second alignment layers may be formed by forming an alignment solution including an alignment agent and a cross-linking agent on the first or second base substrate. The alignment solution is cured at a first temperature to form an alignment layer. The base substrate is exposed to light or an electron beam to align the alignment layer. The alignment layer is baked at a second temperature. The first temperature is lower than a cross-linking reaction temperature of the cross-linking agent.
