Abstract: A display device includes including emission areas, a non-emission area. Light emitting elements are disposed on a substrate in the emission areas. A bank is disposed on the substrate in the non-emission area of the substrate and includes openings corresponding to the emission areas. Color conversion patterns are disposed in the openings of the bank and converts a wavelength band of light incident from the light emitting elements to emit light. Organic patterns are disposed on the color conversion patterns and are separated from each other. Color filters are disposed on the organic patterns. The color filters are sequentially stacked in a space between the organic patterns in the non-emission area.

Abstract: A display device includes a substrate, a display element layer disposed on a first surface of the substrate and including a light emitting element that emits light, and a pixel circuit layer disposed on the display element layer and including a transistor electrically connected to the light emitting element. The display element layer includes a first contact electrode electrically connected to a first end of the light emitting element, and a second contact electrode electrically connected to a second end of the light emitting element. The pixel circuit layer includes a reflective layer disposed on the display element layer and overlapping the light emitting element. One of the first contact electrode and the second contact electrode is electrically connected to the transistor. The reflective layer reflects the light emitted from the light emitting element toward a second surface of the substrate.
