Abstract

A projector includes a light emitting device and a light modulator. The light emitting device includes first and second semiconductor layers respectively electrically connected to first and second electrodes, a light emitting layer generating light by having a current injected thereinto, and a third electrode connected to the second electrode. The second electrode transmits the light generated in the light emitting layer. The third electrode has less resistivity than the second electrode, and includes first conductive sections arranged in a first direction. The light modulator includes pixels, and adjacent pixels are spaced apart by gaps. The arrangement pitch of the first conductive sections in the first direction is a multiple of the arrangement pitch of the gaps in the first direction. The shadows of the first conductive sections generated by the light emitted from the light emitting device are cast onto the gaps.
