Patent ID: 8436850

Claim:
A pixel comprising: an organic light emitting diode coupled between a first power supply and a second power supply; a first transistor coupled between the first power supply and the organic light emitting diode and of which a gate electrode of the first transistor is coupled to a first node; a second transistor coupled between a first electrode of the first transistor and a data line and of which a gate electrode of the second transistor is coupled to a current scanning line; a storage capacitor coupled between the first power supply and the first node; and a boosting capacitor coupled between the first node and the current scanning line, wherein the boosting capacitor comprises: a semiconductor layer, a first conductive layer overlapping the semiconductor layer at an overlapping portion, and a first insulating film therebetween, and wherein the semiconductor layer comprises: a main body portion, a contact portion outside the overlapping portion and coupling the boosting capacitor with another component, and a connecting portion integrally provided with the main body portion and the contact portion to couple the main body portion with the contact portion at an interface of the first conductive layer and having a width smaller than that of the main body portion and the contact portion.
