A potential on a control terminal of a driver transistor is controlled and
a drive current corresponding to the potential is supplied to an organic
electroluminescence element. A drive controlling transistor is inserted
between the driver transistor and the organic electroluminescence element
and the drive current is switched on and off by the drive controlling
transistor. A short-circuiting transistor is provided which controls
whether or not the driver transistor is to be diode-connected. A
selection transistor controls whether or not a data signal from a data
line is to be supplied to the control terminal of the driver transistor.
A capacitor is placed between the selection transistor and the control
terminal of the driver transistor and a connection between a terminal of
the capacitor on the side of the selection transistor and a predetermined
power supply is switched on and off by a potential controlling
transistor.
