Abstract
Official abstract text for this publication.
Provided is an organic EL display device which includes an insulating surface, an anode electrode formed over the insulating surface, an organic layer formed over the anode electrode; a cathode electrode formed over the organic layer; and a photochromic layer in contact with the cathode electrode or the anode electrode, where the photochromic layer has a light-absorbing property with respect to a specific wavelength region.
First claim
Opening claim text (preview).
What is clamed is: 1 . An organic EL display device comprising: an insulating surface; an anode electrode over the insulating surface; an organic layer over the anode electrode; a cathode electrode over the organic layer; and a photochromic layer in contact with the cathode electrode or the anode electrode, the photochromic layer having a property of absorbing light of a specific wavelength region. 2 . The organic EL display device according to claim 1 , wherein a transmittance of the photochromic layer decreases with an increasing amount of light irradiated to the photochromic layer and increases with a decreasing amount of light irradiated to the photochromic layer. 3 . The organic EL display device according to claim 1 , wherein the organic layer has a tandem structure in which a plurality of light-emitting layers are stacked. 4 . The organic EL display device according to claim 1 , wherein the photochromic layer is located over the cathode electrode. 5 . The organic EL display device according to claim 1 , further comprising a reflective metal layer between the insulating surface and the anode electrode, wherein the photochromic layer is located between the reflective metal layer and the anode electrode. 6 . The organic EL display device according to claim 1 , further comprising a plurality of pixels, wherein the organic layer is located in each of the plurality of pixels, and wherein the photochromic layer is arranged so as to be shared by the plurality of pixels. 7 . The organic EL display device according to claim 1 , wherein the photochromic layer includes a metal oxide including at least one of elements selected from Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Nb, Mo, Ru, In, Sn, Sb, Ta, W, Re, Os, Ir, and Bi. 8 . The organic EL display device according to claim 1 , wherein the photochromic layer includes one of a diarylethene compound, a spiropyran compound, a spiroperimidine compound, a viologen compound, and an azobenzene compound. 9 . The organic EL display device according to claim 1 , wherein the diarylethene compound is a stilbene compound. 10 . The organic EL display device according to claim 1 , wherein the photochromic layer has a light-absorbing property with respect to light of a wavelength region from 400 nm to 500 nm.
