FILTER FOR ORGANIC ELECTROLUMINESCENT DISPLAY ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a filter for an organic electroluminescent display element which can alleviate a decrease in durability due to an ultraviolet ray and partial visible light ray. SOLUTION: The filter for the display element interrupts the light having a wavelength of 200-390 nm or preferably 300-410 nm. The light shutting-off filter preferably has an absorptance of 90% or more of the ultraviolet having a wavelength of 410 nm or less. COPYRIGHT: (C)2004,JPO
