Abstract: A display device for improving an outcoupling efficiency of emitted light is disclosed. The display device includes a substrate, a subpixel arranged on the substrate, the subpixel including an organic light emitting diode having an emission portion that emits light, a first passivation layer disposed on the organic light emitting diode, at least one lens positioned on the first passivation layer, the at least one lens disposed in a position corresponding to the emission portion of the organic light emitting diode, a cover layer covering the at least one lens, and a second passivation layer disposed on the cover layer. A refractive index of the at least one lens is greater than a refractive index of the cover layer.

Abstract: A display device includes a display panel including a display area from which an image is output, and the display area includes a camera area overlapping a camera disposed below a rear face of the display panel. The display device provides an imaging function achieve by the camera. The camera area includes a unit pixel area for displaying an image and a transmissive area for transmitting light therethrough. Thus, a separate area that overlaps the camera and does not display an image does not need to be present in the display area. Accordingly, increase in a bezel width and deformation of the display area due to the camera may be prevented.
