Abstract
The light-emitting device includes a first lower electrode, a second lower electrode, a partition, a layer with high conductivity, light-emitting layers, and an upper electrode. The conductivity of the layer with high conductivity is higher than the conductivity of each of the light-emitting layers and lower than the conductivity of each of the lower electrodes and the upper electrode. The partition includes a first slope located on a first lower electrode side and a second slope located on a second lower electrode side. The thickness of the layer with high conductivity located over the first slope in a direction perpendicular to the first slope is different from the thickness of the layer with high conductivity located over the second slope in a direction perpendicular to the second slope.
