Patent ID: 7122969

Claim:
A light emitting device comprising: a scan line; a signal line intersecting with the scan line; a first to a n-th power supply lines; a first power source; a second power source; and a plurality of pixels, wherein each of the plurality of pixels comprises: a light emitting element; a first transistor electrically connected to the second power source; and a second transistor electrically connected to the signal line; wherein the first power source, the first transistor, the second transistor, and the light emitting element are electrically connected in series, wherein a first region of a gate electrode of the first transistor is electrically connected to a k-th power supply line, wherein a second region of the gate electrode of the first transistor is electrically connected to a (k+1)-th power supply line, wherein n is a natural number, and wherein k is a natural number less than n.
