摘要： A display device includes: pixels each including a light-emitting element; scan lines and signal lines; a scan line drive circuit applying a selection pulse to each of the scan lines in succession; and a signal line drive circuit writing video signals to respective selected pixels through switching a gray-scale interpolation voltage, a basic voltage, and a video signal voltage to apply each voltage selected by switching to each of the signal lines. The signal line drive circuit performs gray-scale interpolation on a light emission luminance level for each of the light emitting elements through setting the video signal voltage to a fundamental gray-scale voltage, and through varying the gray-scale interpolation voltage. The scan line drive circuit starts and completes an application of the selection pulse during each of a period of a gray-scale interpolation voltage, a period of a basic voltage and a period of a video signal voltage.
