<p>A current control circuit (300) is provided between a power source circuit (200) and a power source line VL which supplies a drive current to an organic EL element (50) provided in each emissive pixel of a display panel. An amount of current flowing from the power source circuit (200) to the power source line VL is detected, and when the amount of current increases, a power source voltage Vdd to be applied to the power source line VL is decreased, thereby decreasing a current flowing thorough the organic EL element (50). Alternatively, contrast or brightness level of display data to be supplied to each EL element (50) is controlled in accordance with the detected amount of current, so that when the current amount increases, the contrast or brightness level is reduced thereby restricting a current flowing through the organic EL element (50). Thus, the amount of current flowing through the organic EL element (50) can be restricted to thereby prevent excessive power consumption of the display device. <IMAGE></p> |
