Abstract
An organic EL panelis a bendable display panel including a plurality of pixel circuitseach having a light emitting element and a drive element. A data line drive circuitperforms, by driving data lines, an operation of writing a voltage to a control terminal of the drive element and an operation of measuring a current flowing through the drive element for the pixel circuitsselected by a scanning line drive circuit. A bending detection unitdetects a bending state of the organic EL panelbased on a measurement result of the current flowing through the drive element. A correction unitcorrects a video signal VSbased on the detected bending state. With this, the bending state of a screen is detected and a change in brightness or color when the screen is bent is prevented.
