Abstract
A pixel circuit for an electroluminescent element with a first storage capacitor formed overlapping a data line and which comprises a section where a semiconductor thin film constituting the switching transistor or the reset transistor extends, an insulating film, and a metal layer which is connected to the data line as a first terminal. A first terminal of a switching transistor and a first terminal of a reset transistor are connected to the second terminal of the first storage capacitor. The second terminal of the switching transistor is connected to a driving transistor. A second storage capacitor connects the control terminal and the first terminal of the switching transistor. The electroluminescent element is connected to the second terminal of the driving transistor through a light emission controlling transistor.
