Abstract

A display device includes a substrate comprising emission and non-emission areas. A light-emitting element overlaps the emission area and is on the substrate. A thin-film encapsulation layer overlaps with the emission and non-emission areas and is on the light-emitting element. A touch sensor layer is on the thin-film encapsulation layer. The touch sensor layer comprises a first conductive layer on the thin-film encapsulation layer. A touch insulating layer is on the first conductive layer. A second conductive layer is on the touch insulating layer. The touch insulating layer overlaps with the non-emission area and comprises a first surface facing the thin-film encapsulation layer. A second surface is opposite to the first surface and has a width in a first direction greater than that of the first surface. An inclined surface connects the first and second surfaces. The second conductive layer covers the second surface and the inclined surface.
