ABSTRACT:
A light emitting device includes: a plurality of light emitting elements that emit light to have luminosity depending on the magnitude of a driving signal; a plurality of holding units that are respectively disposed in the plurality of light emitting elements, and respectively hold the driving signal to maintain a magnitude regulated such that the luminosity of the plurality of light emitting elements becomes uniform; and a plurality of supply units that are respectively disposed in the plurality of light emitting elements, and supply the driving signal, which is held by the holding units to have a certain magnitude for a period of time according to a gradation of light to be emitted, to a corresponding light emitting element.
