Abstract:
An organic LED display device comprising: thin film transistors in which a plurality of gate lines and a plurality of data lines intersecting said plurality of gate lines are provided on a substrate, pixels are defined by said plurality of gate lines and said plurality of data lines, and a gate scanning signal is applied to said pixels through said gate lines, respectively; and light emitting devices each of which emits light by a driving current, which is caused to flow between an associated one of pixel electrodes formed in correspondence to said pixels and an associated one of counter electrodes opposite to the respective pixel electrodes, in accordance with a data signal which is supplied from the associated one of said data lines synchronously with a timing signal when the associated one of said thin film transistors becomes the conducting state,wherein each of said light emitting devices is an organic LED device, and for a part of a period of time when the associated one of said thin film transistors is in the non-conducting state, the associated one of said organic LED devices is in the non-light emission state, and is applied with a bias voltage having a polarity reverse to the polarity of said bias voltage applied to said associated organic LED device in the light emission state.
