  • DISPLAY DEVICE
    Publication number: 20240016025
    Abstract: A display device including: a first light-emitting opening, a second light-emitting opening, a third light-emitting opening, and a light-receiving opening; wherein a first color emission area corresponds to the first light-emitting opening; a second color emission area corresponds to the second light-emitting opening; a third color emission area corresponds to the third light-emitting opening; and a light detection area corresponds to the light-receiving opening; and when the first color emission area, the second color emission area, and the third color emission area are viewed at a first point having a first viewing angle with respect to a normal line of a base layer, a sensing electrode shields each of two emission areas among the first color emission area, the second color emission area, and the third color emission area or one of the first color emission area, the second color emission area, and the third color emission area.
