Display panel and display device comprising the same
Disclosed is a display panel and a display device capable of reducing the reflection of external light. The display panel includes a touch sensor, disposed on an encapsulation unit, and an antireflective film disposed in a non-emission area of the touch sensor so as to overlap each other, whereby it is possible to reduce external light from being incident on the touch sensor and a routing line, and therefore it is possible to reduce the reflectance of external light without using an expensive polarizing plate.
1. A display device comprising:
a light-emitting element on a substrate;
an encapsulation unit on the light-emitting element, the encapsulation unit including at least one inorganic encapsulation layer and at least one organic encapsulation layer;
a touch sensor on the encapsulation unit; and
a black layer on the touch sensor, the black layer located in a non-emission area that excludes an emission area in which the light-emitting element is disposed.
2. The display device according to claim 1 , wherein the black layer overlaps the touch sensor.
