Abstract: With the use of pixel control parts for controlling display elements in response to display data using a display-use voltage source and display control parts for supplying the display data to the pixel control parts, the display data is displayed on a display part. Further, the display data is corrected by detecting states of the display elements.

Accordingly, it is possible to perform a display while maintaining the maximum brightness even when the display element is degraded. Further, the contrast can be maintained by correcting the gray scales of the display data by performing only the digital calculation.
