Abstract
A light-emitting device () is provided with: a substrate (); a light-emitting region including a light-emitting portion () formed to contact a first electrode layer () and a second electrode layer (); and plural concave portions (). The light-emitting portion contacting at least the first electrode layer and the dielectric layer in the concave portion. The light-emitting device further comprises a terminal (anode terminal) () formed outside the light-emitting region, and connecting one of the first electrode layer () and the second electrode layer () having larger sheet resistance to a power supply. In the light-emitting region, the plural concave portions () are formed such that the sum, per unit area, of a contour length of the planar shapes of the concave portions () on an upper face of the dielectric layer () increases from a region near the terminal () towards a region far from the terminal ().
