Patent ID: 8785948

Claim:
A light-emitting device, the light emitting device comprising: a light-emitting element that is disposed above a plane of a substrate; a power supply line that is disposed above the plane of the substrate, the power supply line having a first part which extends in a first direction; a first transistor that is disposed above the plane of the substrate, the first transistor having a first source, a first drain, and a first gate electrode, the first transistor controlling an electrical connection between the power supply line and the light-emitting element; a second transistor that is disposed above the plane of the substrate, the second transistor controlling an electrical connection between the first gate electrode and one of the first source and first drain, the second transistor having a second source and a second drain; and a connecting portion that electrically connects the first gate electrode and one of the second source and the second drain, the connecting portion that has a first side and a second side which intersects the first side and extends in the first direction, the length of the second side being longer than the length of the first side.
