Abstract

A display device includes at least one pixel including a plurality of sub-pixels, and a linear sensor electrode extending along a boundary of the plurality of sub-pixels and surrounding a periphery of the at least one pixel. The sensor electrode has at least one cut-off portion at the boundary of the plurality of sub-pixels. The sensor electrode can include a first sensor electrode extending along the boundary of a plurality of sub-pixels and a second sensor electrode that surrounds the periphery of at least one pixel continuous from the first sensor electrode, and the cut-off portion can be located at the boundary of the first sensor electrode with the second sensor electrode.
