Light absorption filter, optical filter, manufacturing method for optical filter, organic electroluminescent display device, inorganic electroluminescent display device, and liquid crystal display device

Abstract

A light absorption filter including a support, and a dye layer containing a resin, a dye having a main absorption wavelength band in a wavelength range of 400 to 700 nm, and a compound that generates a radical upon ultraviolet irradiation, the dye layer being provided on the support, in which a layer that inhibits diffusion of a component in the dye layer to the support is provided between the support and the dye layer, an optical filter using the light absorption filter, a manufacturing method for an optical filter, an organic electroluminescent display device, an inorganic electroluminescent display device, and a liquid crystal display device.
