To solve the problem that it takes too much time to start up the light emitting at charging start, in a driving circuit and a method for a panel display device.
A driving circuit for a panel display device drives organic EL elements PEm and n which are placed at each cross point of a plurality of data line, SEGm and a plurality of scanning lines COMn. A driving circuit for the panel display device has a voltage control circuit 12 which connects the data line SEGm which is selected during a start up period before a load carrying capacity of organic EL elements PEm and n are charged to the voltage value necessary for light emitting, with a data line power source 30, and a driving control circuit 10 which connects the data line SEGm with a constant current source 11 after the start up period.
