    Abstract: A display device includes a display portion including a first surface, from which light is emitted in a first direction, and a second surface opposite to the first surface, a first optical portion disposed on the first surface, and a second optical portion disposed on the first surface to be spaced apart from the first optical portion in a second direction crossing the first direction. Each of the first and second optical portions includes a multi-channel lens through which the light from the first surface passes, a first infrared light source, a first camera, and a first lens frame coupled to the multi-channel lens in the first direction to support at least a portion of the multi-channel lens. The first lens frame may include a first recess structure in which the first infrared light source is disposed and a second recess structure in which the first camera is disposed.

    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 includes a display panel including a display area in which an image is displayed, and a light unit that includes: a light guide plate including a light receiving surface and a light emitting surface; a light source spaced apart from the light receiving surface while facing the light receiving surface and overlapping the display area; and a light diffusion member extending between the light receiving surface and the light source. The light diffusion member includes at least one of a first pattern formed on a surface of the light diffusion member facing the light emitting surface, and a second pattern formed on another surface of the light diffusion member, thereby implementing uniform brightness across the whole surface of the display panel.
