Claim Text:
1. An organic electroluminescent display device comprising: an element substrate; a thin film transistor formed on the element substrate; an insulation layer formed on the thin film transistor; a plurality of organic electroluminescent light-emitting elements disposed on the insulation layer; an insulation bank formed on the insulation layer, the insulation bank including a first bank and a second bank; and a sealing film disposed on each of the organic electroluminescent light-emitting elements, the first insulation bank, and the second insulation bank, wherein each of the organic electroluminescent light-emitting elements includes an anode disposed on the element substrate, wherein each of the organic electroluminescent light-emitting elements is arranged between the first bank and the second bank, wherein the sealing film includes a light-transmittance-reducing layer colored in black to form a gray filter, wherein the gray filter is configured to spread continuously from a first region above the first bank to a second region above the second bank through a third region above each of the organic electroluminescent light-emitting elements, wherein the gray filter covers the plurality of organic electroluminescent light-emitting elements if plan view, and wherein the gray filter is configured to attenuate light transmitting from each of the organic electroluminescent light-emitting elements while letting the light pass outside of the organic electroluminescent display device.
