Abstract: Discussed is a display device including a substrate, a circuit element on the substrate, a light emitting element electrically connected to the circuit element and including a first electrode, a light emitting layer, and a second electrode. A bank can define the emission area where the first electrode is exposed, and define the non-emission area where the bank is located, a taper pattern can be on the substrate and interposed between the circuit element and the bank at the non-emission area. The bank can include an incline extending from an edge of the emission area to a predetermined distance into the non-emission area, the incline of the bank defining a taper area, and the taper pattern can be adjacent to or overlap the taper area.

Abstract: The present disclosure provides a display device including a plurality of subpixels disposed in a display area for displaying images, each of the subpixels including a light emitting element, a driving transistor for driving the light emitting element. The display area may include a first area, a second area surrounding the first area, and a third area between the first area and the second area. First, second, and third subpixels among the plurality of subpixels are disposed in the first, second, and third areas, respectively. When first data corresponding to the first subpixel is equal to second data corresponds to the second subpixel, the luminance of the first subpixel may be greater than the luminance of the second subpixel.
