A gamma-correction circuit is formed by a switch circuit (52) for receiving a reset pulse and connecting a terminal pin (XR) to a predetermined potential line, a correction data generation circuit (7) for generating correction data (TDi) for correcting a light emission period in accordance with display data in order to subject the luminance of an OEL element (9) to the gamma-correction, and a reset pulse generation circuit (51) for receiving a timing control signal (TP) and the correction data (TDi) and generating a reset pulse of the pulse width corresponding to the gamma-correction. By providing the gamma-correction circuit corresponding to the terminal pin (XR), it is possible to suppress the area occupied by the organic EL drive circuit and the gamma-correction circuit of the organic EL display device. |
