ABSTRACT:
To suppress an off leak current of a switching element arranged along a data line to control degradation of tonal gradation in an arrangement in which an organic electro-luminescent element OLED is driven using a current programming method, a first switching element is set to be in a non-conductive state and a second switching element is set to be in a conductive state during a normal mode. During a test mode, the first switching element is set to be in a conductive state while the second switching element is set to be in a non-conductive state.
