Abstract
According to one embodiment, a display device includes touch detection electrodes, and a driver. The touch detection electrodes include stripe common electrodes serving as electrodes for display. The driver includes a first, second, and third drivers for driving each of the stripe electrodes. Auxiliary lines connect each of the stripe electrodes to the third driver. The first and second drivers are provided along shorter sides of the stripe electrodes. The third driver is provided along a longer side of the stripe electrodes.
Claims14
A display device comprising:
- a display unit configured to display an image;
- an electrode unit provided in a display area of the display unit and configured to detect a touch by an external object;
- and
