Abstract: A display panel includes first, second, and third color light emitting areas and a non-light emitting area disposed among the first, second, and third color light emitting areas. First, second, and third openings corresponding to the first, second, and third color light emitting areas are defined in an input sensor. A sensing electrode includes a first line area and a second line area facing each other in a first direction around each of the first, second, and third openings and a third line area and a fourth line area facing each other in a second direction intersecting the first direction. A distance between the first color light emitting area and the first line area is less than a distance between the second and third color light emitting areas and the first line area.

Abstract: A display device includes a base layer, a pixel defining layer, a light emitting element comprising a light emitting layer, and an encapsulation layer disposed on the light emitting element. The encapsulation layer includes a first optical layer, a second optical layer disposed on the first optical layer, a stabilization layer disposed on the second optical layer, and an optical control layer disposed on the stabilization layer. A refractive index of the first optical layer is greater than a refractive index of the second optical layer, and a refractive index of the stabilization layer is greater than each of the refractive index of the second optical layer and a refractive index of the optical control layer. A thickness of the stabilization layer is greater than a thickness of the first optical layer and a thickness of the second optical layer.

Abstract: A display device includes a substrate including a light emitting area and a non-light emitting area surrounding the light emitting area, a conductive line on the substrate to pass through the light emitting area and including an overlapping portion overlapping the light emitting area, and a pixel electrode on the conductive line and overlapping the overlapping portion of the conductive line. The overlapping portion of the conductive line includes a body part having a polygonal planar shape and having an area smaller than an area of the light emitting area, a first protrusion part protruding in a first direction from the body part to a boundary between the light emitting area and the non-light emitting area, and a second protrusion part protruding in a second direction opposite to the first direction from the body part to the boundary between the light emitting area and the non-light emitting area.
