Abstract

Disclosed is a light emitting device wherein a current control means is provided for supplying a driving current to a surface-emitting body, which has an organic EL layer, and a part of a developed section of the surface-emitting body. Energy is saved and the service life is lengthened by making the developed section emit light.
