Abstract
A display device is disclosed. In an embodiment a display device includes a carrier including a plurality of switches, a semiconductor layer sequence arranged on the carrier, the semiconductor layer sequence comprising an active region configured to generate primary radiation and forming a plurality of pixels, wherein each switch is configured to control at least one pixel and an optical element arranged on each pixel on a radiation exit surface of the semiconductor layer sequence facing away from the carrier.
Claims18
A display device comprising:
- a carrier comprising a plurality of switches;
- a semiconductor layer sequence arranged on the carrier, the semiconductor layer sequence comprising an active region configured to generate primary radiation and forming a plurality of pixels, wherein each switch is configured to control at least one pixel;
- an optical element arranged on each pixel on a radiation exit surface of the semiconductor layer sequence facing away from the carrier;
- and
- separating bodies on a top side of each pixel in direct contact with the pixel, wherein the separating bodies are impermeable to radiation emitted during operation of the display device, each separating body completely surrounding the optical element in a lateral direction, and wherein the top side of each pixel is free of the separating body in places where the pixel is covered by the optical element.
