Abstract: A display device includes: a display panel including a substrate having first and second opposing surfaces and a light emitting element disposed on the first surface of the substrate, the display panel having a transmission area through which light is transmitted from outside the display device; a sensor facing the surface of the substrate and configured to sense light received through the transmission area; and an anti-reflective member disposed between the sensor and the substrate and to transmit light such that reflection of applied light is reduced. The anti-reflective member overlaps the transmission area when viewed in a direction normal to the first and second surfaces of the substrate.

Abstract: A display device includes a first base substrate including a light-emitting area and a non-light-emitting area around the light-emitting area, a wavelength conversion pattern on the first base substrate in the light-emitting area, and a light-emitting element layer on the wavelength conversion pattern. The light-emitting element layer includes a pixel electrode including a first conductive pattern between the wavelength conversion pattern and the first base substrate, and a second conductive pattern on the wavelength conversion pattern and spaced apart from the first conductive pattern, an organic light-emitting layer on the second conductive pattern, and a common electrode on the organic light-emitting layer.

Abstract: A display device includes a substrate, a partition wall disposed on the substrate and having a plurality of openings, a first emission layer, a second emission layer, and a third emission layer respectively disposed in an opening of the partition wall and emitting light of different colors, a light blocker disposed on the emission layers and including a plurality of openings respectively overlapping the first emission layer, the second emission layer, and the third emission layer, and a color filter disposed in the opening of the light blocker. A separation distance between one edge of the partition wall contacting the second emission layer and the light blocker is greater than a separation distance between the one edge of the partition wall contacting the first emission layer and the light blocker.
