Abstract: A display device includes: a display panel including a substrate, where the display panel is divided into a first display region in which a plurality of first pixels is disposed and a second display region in which a plurality of second pixels is disposed; and a sensor overlapping the second display region of the display panel. The second display region includes a plurality of unit pixel blocks, each including two second pixels adjacent to each other in a first direction and two second pixels adjacent to each other in a second direction intersecting the first direction, and a transmissive region through which light is transmitted. A distance between two unit pixel blocks adjacent to each other in the first direction is greater than a distance between two unit pixel blocks adjacent to each other in an oblique direction inclined to the first direction.

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.
