COLOR CHANGING FILTER SUBSTRATE AND ORGANIC MULTI-COLOR LUMINESCENT ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a color conversion filter substrate suppressing the occurrence of moisture causing the characteristic deterioration in an organic multi- color luminescent element and provide the organic multi-color luminescent element maintaining a stable luminescence characteristic over a long period. SOLUTION: The steam permeability of a gas barrier layer 5 covering color conversion filter layers 2-4 formed on a transparent support substrate 1 in a color conversion filter substrate is set to 1.0 g/m2.24 h or below. The film thickness tPL of the gas barrier layer on the color conversion filter layers is set to the range shown by expression 0<tPL<0.1W, wherein, W indicates the minimum width of the pixel.
