Abstract:
An organic EL display panel includes: a P-type drive transistor having a gate connected to a capacitor and a drain connected to an organic EL element; an N-type drive transistor having a gate connected to the capacitor and a source connected to the organic EL element; a first power source line for applying a first voltage to the P-type drive transistor; a second power source line for applying, to the N-type drive transistor, a second voltage higher than the first voltage. The P-type drive transistor has characteristics such that a first gate voltage value corresponding to a predetermined current value in current-voltage characteristics of the organic EL element is a minimum voltage of the data voltage, and the N-type drive transistor has characteristics such that a second gate voltage value corresponding to the predetermined current value is greater than a third gate voltage value corresponding to a minimum current value of the organic EL element.
