Abstract: One embodiment of the present invention relates to a light-emitting device comprising an insulating surface; a lower electrode over the insulating surface; a protrusion over the insulating surface having a sidewall sloping toward the lower electrode; a light-transmitting partition overlapping with an end portion of the lower electrode and the sidewall of the protrusion; and a light-emitting element including the lower electrode, an upper electrode overlapping with the lower electrode, and a layer containing a light-emitting organic compound between the lower electrode and the upper electrode. In the light-emitting device, the sidewall of the protrusion can reflect light emitted from the light-emitting element. As a result, the light-emitting device that has reduced power consumption is provided.
