Abstract
An EL element () having an organic emissive layer or the like between the anode and cathode is used as an element to be driven, and an element driving TFT () for controlling the current supplied to the EL element () and a compensation thin film transistor () having an opposite conductive characteristic as the element driving TFT () are provided between the EL element () and the power supply line VL. With this structure, variation in the current supplied to each EL element () is reduced.
