The present invention provides a light-emitting device including a pixel block including light-emitting elements disposed on a long substrate and aligned in the longitudinal direction of the substrate, pixel circuits connected to the light-emitting elements, a control signal line connected to the pixel circuits, and a pixel block select circuit connected to the control signal line and configured to output a control signal to the pixel circuits. The pixel circuits are divided into a plurality of groups. The control signal line includes first and second interconnection portions. The first interconnection portion is disposed along the longitudinal direction of the substrate and connected to the pixel circuits. The second interconnection portion is disposed in a region between the groups and connected to the pixel block select circuit. The first interconnection portion and the second interconnection portion are connected to each other in the region between the groups.
