  • Publication number: 20240008338
    Abstract: A display device includes a substrate, a pixel electrode disposed on the substrate, a bank layer which is disposed on the pixel electrode and in which a pixel opening overlapping the pixel electrode is defined, an encapsulation layer disposed on the pixel electrode and the bank layer, a sensing electrode disposed on the encapsulation layer, a first insulating layer which is disposed on the sensing electrode and in which an opening overlapping the pixel opening is defined, and a second insulating layer disposed on the first insulating layer and having a higher refractive index than a refractive index of the first insulating layer. The opening of the first insulating layer includes a first edge and a second edge separated from an edge of the pixel opening and extending in different directions from each other and a first extension part disposed at a portion where the first edge and the second edge meet.
