Touch sensor-equipped display device

Abstract

A touch sensor-equipped display device is provided in which dividing lines for dummy electrodes provided between touch detection electrodes are not recognizable. The touch sensor-equipped display device includes: a display panel that includes a display function layer interposed between a first substrate and a second substrate, the display function layer including a plurality of display pixels arranged in matrix; a plurality of touch drive electrodes arranged between the first substrate and the second substrate so as to be arrayed in a first direction, each of the touch drive electrodes extending in a second direction that intersects with the first direction at a right angle; a plurality of touch detection electrodes arranged on a surface of the first substrate, the surface being on an opposite side with respect to the touch drive electrodes, so as to be arrayed in the second direction, each of the touch detection electrodes extending in the first direction; and a dummy electrode arranged between adjacent ones of the touch detection electrodes. A slit is provided in the dummy electrode, the slit being repeatedly bent in a zigzag shape, while extending in the first direction. The dummy electrode is divided by, as a dividing line, a line obtained by extending either a first edge or a second edge, the first edges and the second edges forming the slit in the zigzag shape, so that the dummy electrode should not be provided across a plurality of the touch drive electrodes.
