ABSTRACT:
A driver IC (4) and a current driver circuit (40) are shared by a first organic EL panel (2) and a second organic EL panel (3). Therefore, not like conventional cases, the current driving circuit (40) on a side not selected is not necessarily in a standby state, and power consumption can be reduced. In a case where the first and second organic EL panels are passive matrix type, a first diode is provided between each column line of the first and the second organic EL panels and corresponding each terminal pin so as to prevent a reverse flow.
