Abstract: A display device can include a display panel having a first display area in which first pixels are disposed, and a second display area in which second pixels and a light-transmission area disposed between the second pixels are disposed, and a sensor disposed to correspond to the second display area. One of the second pixels includes sub-pixels. The display panel can include a circuit layer, a light emitting element layer disposed on the circuit layer, and an anti-reflection layer disposed between a planarization layer of the circuit layer and an anode electrode of the light emitting element layer. Further, a space is formed between an anode electrode of one sub-pixel and an anode electrode of another adjacent sub-pixel, and a path of light directed to the sensor through the space is changed by the anti-reflection layer. Accordingly, the display device can minimize the amount of light reaching the sensor.

Abstract: A display device and a method for manufacturing the display device are provided. The display device comprises a substrate including a first light-emitting portion and a second light-emitting portion spaced apart from each other, a reflective layer spaced apart from each of the first and second light-emitting portions and surrounding the second light-emitting portion, a first light-emitting element including a first light-emitting layer in the first light-emitting portion, and a second light-emitting element including a second light-emitting layer in the second light-emitting portion, wherein the second light-emitting layer emitting light having a wavelength different from light emitted from the first light-emitting layer.
