    Abstract: A display device includes a display unit including a first surface emitting first light, a second surface opposite to the first surface, a first transmission area transmitting light incident on the first surface, and a second transmission area transmitting the light incident on the first surface. The display device includes a first lens on the first surface and including a first hole overlapping the first transmission area in a thickness direction, a second lens on the first surface and spaced apart from the first lens and including a second hole overlapping the second transmission area in the thickness direction, and light sources emitting second light and disposed on the first and second lenses. The display device includes a first camera sensor on the second surface and overlapping the first transmission area, and a second camera sensor on the second surface and overlapping the second transmission area.

    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 substrate, a bank disposed on the substrate and having a multi-layered structure having an opening, a light emitting element disposed in the opening and including a pixel electrode, a light emitting layer, and a common electrode, a thin film encapsulating layer disposed on the light emitting element and the bank, a micro lens disposed on the thin film encapsulating layer and overlapping the light emitting element, and a light control layer disposed on the thin film encapsulating layer and surrounding the micro lens. A refractive index of the micro lens is greater than a refractive index of the light control layer.
    The pixel electrode is disposed in the opening and extends along an inner surface of the bank, and the light emitting layer extends along the inner surface of the bank on the pixel electrode.
