Abstract:
A display device includes a display region including display pixels, a control circuit, a first power line pattern, and a second power line pattern. The display region includes a first region and a second region having a lower display pixel density than the first region. The control circuit is configured to supply pixel circuits in the first region with a first power supply potential through the first power line pattern, supply pixel circuits in the second region with a second power supply potential higher than the first power supply potential through the second power line pattern, and supply light-emitting elements of the display pixels in the second region with driving current higher than driving current for the display pixels in the first region for a same grayscale level specified in image data.
