Zusammenfassung:An organic EL panel 10 is a display panel which can be bent and includes a plurality of pixel circuits 60, each of which has a light emitting element and a driving element. A data line driving circuit15 performs an operation for writing a voltage to a control terminal of the driving element and an operation for measuring the current flowing through the driving element by driving a data line withrespect to the pixel circuit 60 selected by a scan line driving circuit 14. A bending detecting unit 90 detects the bending state of the organic EL panel 10 on the basis of the result of measuring thecurrent flowing through the driving element. A correcting unit 80 corrects an image signal VS1 on the basis of the detected bending state. Accordingly, the bending state of a screen is detected and achange in brightness or color is prevented when the screen is bent. 有机EL面板10是包括多个像素电路60的可弯曲的显示面板,多个像素电路60具有发光元件和驱动元件。数据线驱动电路15通过驱动数据线,对被扫描线驱动电路14选择的像素电路60,进行对驱动元件的控制端子写入电压的动作和测量驱动元件中流动的电流的动作。弯曲检测部90基于对驱动元件中流动的电流进行测量而得到的结果,检测出有机
