发明名称 Light Emitting Device
摘要 It is an object of the invention to provide a light emitting device which can display a superior image in which luminescent color from each light emitting layer is beautifully displayed and power consumption is lowered in a light emitting element in which light emitting layers are stacked. One feature of the invention is that, in a light emitting element which comprises light emitting layers stacked between electrodes, each distance between each light emitting layer and an electrode is approximately oddly multiplied ¼ wavelength by controlling a thickness of a layer provided therebetween to enhance luminous output efficiency. Another feature of the invention is that a drive voltage is lowered using a high conductive material for the layer compared with a conventional element.
