Abstract:
1. 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 connection with said pixels and an associated one of counter electrodes opposite to the respective pixel electrodes, and each of said pixel electrodes is connected to one of said film transistors, 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 organic LED devices is in the non-light emission state, and when at least one other organic LED device of said display device is in the light emission state, a bias voltage is applied to said associated one organic LED device having a polarity reverse to the polarity of said bias voltage applied to said associated one organic LED device in the light emission state.
