Patent ID: 7868546

Claim:
A light emitting display device comprising: a first substrate having a first interior surface; an array of light emitting units formed on the first interior surface, the array having a top surface facing away from the first substrate; a second substrate placed over the first substrate and the array, the second substrate having a second interior surface, which faces the first substrate; and a desiccant layer placed between the first and second substrates, the desiccant layer comprising a desiccant, a binder, a selective light absorber, and a dispersant, wherein the desiccant comprises at least one of a metal oxide and a metal salt, wherein the at least one of the metal oxide and the metal salt is in a particulate form having an average particle diameter of about 100 nm or less, wherein the dispersant ranges from about 1 to about 100 parts by weight based on 100 parts by weight of the desiccant, and wherein the desiccant, binder, selective light absorber and dispersant are selected such that the desiccant is configured to be substantially transparent with respect to visible light; wherein the selective light absorber comprises at least one compound selected from the group consisting of a porphyrin-based compound, a pyromethene-based compound, a satural absorber phenothiazine-based compound and an azaporphyrin-based compound.
