Patent ID: 8772789

Claim:
A light-emitting device, the light emitting device comprising: a light-emitting element that is disposed above a substrate; a power supply line that is disposed above the substrate; a first transistor that is disposed above the substrate, the first transistor having a first source, a first drain, and a first gate electrode, the first transistor controlling a first electrical connection between the power supply line and the light-emitting element; a second transistor that is disposed above the substrate, the second transistor having a second source, a second drain, and a second gate electrode, the second transistor controlling a second electrical connection between the first gate electrode and one of the first source and the first drain; and a connecting portion that electrically connects the first gate electrode to one of the second source and the second drain, the power supply line including a first power supply line extending in a first direction and a second power supply line extending in a second direction crossing the first direction, and the connecting portion being positioned between the first power supply line and the second power supply line in plan view.
