In order to adequately charge/discharging a parasitical capacitor of a source signal line and program a predetermined current value to a pixel transistor, a relative large current must be outputted from a source excited circuit. However, if a so large current flows through the source signal line, the current value is programmed into pixels, that induces a current large than a needed current passed through an EL component 15. For example, if programing is performed by using a 10 times current, the 10 times current flows through the EL component 15 so that the EL component 15 is lighted with a 10 times lightness. The time for current flowing through the EL component is reduced to 1/10 of a frame (1F) to obtain a predetermined transmitting lightness.
