Patent ID: 8446083

Claim:
A light emitting apparatus including: a plane-shape light emitting area; a power supply area extending along the light emitting area, the power supply area supplying a current to the light emitting area across an edge of the power supply area facing the light emitting area; and a power supply voltage feeding part configured to feed a power supply voltage to the power supply area, the power supply voltage feeding part being connected to the power supply area at a power supply port provided on another edge of the power supply area opposite to the edge facing the light emitting area, wherein the power supply area includes a first non-conductive area surrounded by a conductive area located on a shortest path from a center of the power supply port to the edge of the power supply area facing the light emitting area, so that the difference between the length of the longest path and the length of the shortest path along the conductive area is reduced.
