To sufficiently perform the charge/discharge of the parasitic capacitance of the source signal line and perform the programming of the predetermined current value in the pixel transistor, a larger current must be output from the source driver circuit where the current outputs. However, if such a large current flows into the source signal line, the current value will be programmed in the pixel, and a current larger than the desired current will flows to the EL element (15). For example, if programming is performed by N=10 times current, 10 times current flows to the EL element (15), and the EL element (15) illuminates with a 10 times brightness. Hence, to obtain predetermined brightness, the time for flowing the current to the EL element is set to be 1/10 of 1 frame (1F). By driving in this way, the charge/discharge of the parasitic capacitance of the source signal line can be performed sufficiently, and the predetermined brightness can be obtained.
