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.
