Abstract

A wavelength selective absorption filter contains a resin, a coloring agent, and a compound having at least one polar group of a carboxylic acid ester bond, a carboxylic acid amide bond, a sulfonic acid amide bond, a urethane bond, or a sulfonyl bond and a MW≤1,000 where dye includes at least one of dye A having a main absorption wavelength range at a wavelength of 390 to 440 nm and dye D having a main absorption wavelength range at a wavelength of 680 to 780 nm, a 20% value wavelength A with respect to an absorbance maximal value exhibited by a main absorption wavelength is 455 nm or less where dye A is contained, and a 20% value wavelength D with respect to the absorbance maximal value exhibited by the main absorption wavelength is 640 nm or more where dye D is contained, and a display device.
