Abstract
Disclosed is a display apparatus which can improve the characteristics of TFTs used to select and drive self-emissive elements such as OLEDs. The display apparatus has row electrodes, column electrodes, and a driving unit. The self-emissive elements are formed in regions corresponding to intersections of the row electrodes with the column electrodes. Element driving circuits are formed for driving the self-emissive elements. Each of the element driving circuits includes a selection transistor, a capacitor, and a driving transistor. The driving unit applies a reverse bias to a control terminal of the driving transistor in a non-emission period in which the self-emissive element is not supplied with a driving current.
