Abstract
A drive circuit of an active matrix type organic EL display panel includes a plurality of current drive circuits provided correspondingly to data lines or column pins of the display panel, a plurality of pixel circuits, each of which includes a capacitor and an organic EL element, and a write control circuit. The current drive circuit includes an output pin connected to the data line or the column pin and generates a current for charging the capacitor to a predetermined voltage through the data line or the column pin and a current for initially charging the organic EL element. The write control circuit performs a write control for storing the voltage in the capacitor and a resetting control for of the capacitor written with the voltage.
