Abstract: According to one embodiment, sensor-equipped display device includes a display panel, a first driver, and a second driver. The display panel includes a first electrode, a second electrode and a detection electrode. The first driver delivers a common driving signal to the first electrode and the second electrode at a time of display driving, and selectively writes a write signal to one of the first electrode and the second electrode at a time of sensing driving. The second driver reads, from the detection electrode, a read signal indicative of a variation of a sensor signal occurring between the one of the first electrode and the second electrode, on one hand, and the detection electrode, on the other hand, at the time of the sensing driving.

Abstract: An image quality of a display device is improved. The display device includes: a display unit having a display functional layer; a cover member having a front surface and a back surface positioned on an opposite side of the front surface and covering the display unit; and a polarizing plate having a front surface so as to oppose the back surface of the cover member through a space spreading along the back surface of the cover member. Also, a reflection suppressing layer reducing reflected light which is visually recognized on the display surface side is formed on either one of the back surface of the cover member and the front surface of the polarizing plate.
