Abstract
A display device capable of suppressing the display quality deterioration is provided even if an optically transparent nondisplay area is formed inside the display area of the display panel of the display device. The display device comprises a display panel including signal lines, scanning lines, and pixels that are connected to the signal lines and scanning lines and surrounded by the signal lines and scanning lines. The display panel includes a display area and an optically transparent nondisplay area inside the display area, and a drive circuit for driving the signal lines. The drive circuit includes at least one of a first drive scheme wherein drive voltages are set smaller as distances between adjacent signal lines corresponding to the drive circuit are shorter, a second drive scheme in which the rising speed of drive waveforms are set smaller as distances between adjacent signal lines corresponding to the drive circuit are shorter, and a third drive scheme in which drive times are set longer as distances between adjacent signal lines corresponding to the drive circuit are shorter.
