Abstract
A driver IC () and a current driver circuit () are shared by a first organic EL panel () and a second organic EL panel (). Therefore, not like conventional cases, the current driving circuit () 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.
