摘要 |
In an active matrix EL display device, pixels which are suitable for a constant current drive are structured. The pixel includes a first switch which has one end connected to a source signal line and the other end connected to a current-voltage conversion element, a second switch which has one end connected to the current-voltage conversion element and the other end connected to a voltage holding capacitor and to a voltage-current conversion element, and a pixel electrode connected to the current-voltage conversion element and to the voltage-current conversion element.
