Light-emitting body, light emitting device and light-emitting display
View Patent ↗A light-emitting body of the present invention includes an anode and a cathode at least partly facing the anode with the intermediary of a light-emitting material layer. An auxiliary electrode is formed, via an insulation layer, on the surface of the light-emitting body opposite to the surface where the anode faces the cathode via the light-emitting material layer. The cathode can be formed of a material that corrodes little. The light-emitting body therefore extends the life of a light-emitting device and therefore the life of a light-emitting display.
