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 13 connected to a cathode 12 are provided to surround an effective area 2a outside the effective area 2a where a plurality of pixels 103R, G and B having light-emitting elements are provided. First to third power source lines 103G, 103B and 103R connected to pixel electrodes are provided between the cathode wiring lines 13 and the effective area 2a.
