Abstract: A display device may include a display configured to emit light for displaying an image, a microlens array on the display and configured to collimate the image incident from the display so as to be delivered to the eyes of a user, the microlens array including a refractive index conversion layer in which a refractive index varies from region to region, and an optical path adjustment layer configured to collect light, emitted from the display and transmitted by the microlens array, and to space the display and the microlens array a preset distance apart from each other. Here, the refractive index conversion layer may include a polymer and liquid crystal molecules that interact with the polymer.

Abstract: 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.
