Abstract: According to an aspect, a display device includes: a first panel including pixels; a second panel including light control pixels; and a light source. When any of the pixels is controlled to transmit light in accordance with an input image signal, blurring processing is applied, a blurring area is formed, and light from the light source transmits through the blurring area and the pixel controlled to transmit light and is emitted from the first panel. When a straight line connecting a user viewpoint and the pixel controlled to transmit light has an angle relative to a normal to the first panel, a center of the blurring area is at a position shifted to a side opposite to a reference normal side relative to the normal to the first panel passing through a center of the pixel. The reference normal is a normal to the first panel passing through the viewpoint.

Abstract: The reliability of a display device with an input device is improved. A plurality of detection electrodes (input position detection electrodes) forming an electrostatic capacity between them and a common electrode of a display device to detect an input position are formed on a different substrate from substrates configuring the display device. Moreover, a polarizing plate and the substrate on which the plurality of detection electrodes are formed are adhesively fixed via, for example, an adhesive layer so that the plurality of detection electrodes are fixed so as to be separated apart from the display device. Thus, a distance between electrodes (the detection electrode and a driving electrode) for detecting an input position can be set separately from a thickness of the display device, and therefore, reduction in detection sensitivity (detection reliability) for the input position due to increase in the electrostatic capacity can be suppressed.
