A semiconductor device having a light-emitting element with excellent light-emitting characteristics is provided. The semiconductor device is provided with a first depressed portion or opening portion formed in an insulating film; a first electrode which is formed over the insulating film around the first depressed portion or opening portion, which is positioned in the first depressed portion or opening portion, and which forms a second depressed portion together with the first depressed portion or opening portion; a semiconductor layer of a first conductivity type which is formed over the first electrode and which forms a third depressed portion together with the second depressed portion; a light-emitting layer which is formed over the semiconductor layer of the first conductivity type and which forms a fourth depressed portion together with the third depressed portion; a semiconductor layer of a second conductivity type which is formed over the light-emitting layer and which forms a fifth depressed portion together with the fourth depressed portion; and a second electrode formed over the semiconductor layer of the second conductivity type that forms a bottom surface and a side surface of the fifth depressed portion.
