Abstract
A light-emitting device and an electronic apparatus, which are capable of preventing reduction of the amount of current flowing through light-emitting elements and which have an excellent display characteristic, are provided. Cathode wiring lines connected to a cathode are provided to surround an effective area outside the effective area where a plurality of pixels having light-emitting elements are provided. First to third power source lines connected to pixel electrodes are provided between the cathode wiring lines and the effective area.
Claims22
An electro-optical device, comprising:
- a substrate;
- a functional layer having a light-emitting layer disposed in a pixel display part;
- a first electrode disposed above the substrate, the first electrode being an anode;
- a second electrode disposed so that the light emitting layer is disposed between the first electrode and the second electrode, the second electrode being a cathode;
- a driving transistor that controls a current to the first electrode;
- and
- a power source line configured to supply the current to the first electrode, the power source line being electrically connected to the driving transistor and being disposed under the first and second electrodes, the power source line extending along a first direction, and the power source line having a first edge extending along the first direction and a second edge opposing the first edge, the first edge and the second edge overlapping the first electrode such that the power source line substantially overlaps an entire portion of the first electrode.
