摘要： A display device comprises a substrate, a sub-pixel disposed on the substrate and that includes a pixel electrode, a light emitting layer, and a common electrode, a pixel defining layer that defines the sub-pixel, a capping layer disposed on the pixel defining layer, a micro lens disposed on the capping layer and that overlaps the sub-pixel; and a total reflection pattern disposed on the capping layer and that overlaps the pixel defining layer and surrounds the micro lens. The micro lens has a refractive index greater than a refractive index of the total reflection pattern and less than or equal to a refractive index of the capping layer.

摘要： A head mounted display device includes a lens assembly which changes a path of light; a main display module which outputs a main image and is positioned in front of the lens assembly; a main optical block which shields at least a portion of a light representing the main image such that the light representing the main image faces the lens assembly; a sub-display module disposed on a side of the main optical block and which outputs a sub-image; a sub-optical block positioned on the side of the main optical block and which shields at least a portion of a light representing the sub-image; and a light path converter positioned in the sub-optical block and which changes a path of the light representing the sub-image such that the light representing the sub-image faces the lens assembly.
