Abstract

According to an aspect, a display device with a touch detecting function includes: a display area in which pixels each composed of a plurality of color areas are arranged in a matrix; a touch detection electrode including a first conductive thin wire extending in a first direction; and a dummy electrode including a plurality of second conductive thin wires; a drive electrode having capacitance for the touch detection electrode. Each of the second conductive thin wires includes a plurality of thin wire pieces extending in a direction different from the first direction and is divided by a slit between the thin wire pieces. A color area in the display area with which the slit overlaps has a different color from a color area in the display area with which a slit closest to the slit in a second direction orthogonal to the first direction overlaps.

Claims (31)

1. A display device with a touch detecting function comprising:

a display area in which pixels each composed of a plurality of color areas are arranged;

a touch detection electrode and a dummy electrode on the display area; and

a drive electrode forming a capacitance with the touch detection electrode when a drive signal is applied, wherein

the touch detection electrode includes

a pair of first electrodes extending in parallel, and

a pair of conductive parts extending in parallel, one of the conductive parts connecting first ends of the first electrodes, and the other of the conductive parts connecting second ends of the first electrodes,

a first longitudinal direction of the pair of first electrodes intersects a second longitudinal direction of the pair of conductive parts,

the one of the conductive parts, the dummy electrode, and the other of the conductive parts are arranged in the first longitudinal direction in an order as listed,

the dummy electrode is located between the pair of first electrodes in the second longitudinal direction, and

the dummy electrode is surrounded by the pair of first electrodes and the pair of conductive parts of the touch detection electrode, and located in a closed area formed of the pair of first electrodes and the pair of conductive parts in a planar view.

2. The display device with a touch detecting function according to claim 1 , wherein

each of the pair of the first electrodes further includes

a pair of first conductive thin wire pieces extending in a first direction in parallel, and

a pair of second conductive thin wire pieces extending in a second direction crossing the first direction in parallel.

3. The display device with a touch detecting function according to claim 2 , wherein

the dummy electrode includes

a pair of third conductive thin wire pieces extending in the first direction in parallel, and

a pair of fourth conductive thin wire pieces extending in the second direction in parallel.

4. The display device with a touch detecting function according to claim 3 , wherein

one of the third conductive thin wire pieces is connected to one of the fourth conductive thin wire pieces, and

the other of the third conductive thin wire pieces is connected to the other of the fourth conductive thin wire pieces.

5. The display device with a touch detecting function according to claim 3 , wherein

the dummy electrode further includes

a pair of fifth conductive thin wire pieces extending in a first direction in parallel, and

a pair of sixth conductive thin wire pieces extending in a second direction crossing the first direction in parallel.

6. The display device with a touch detecting function according to claim 5 , wherein
