Title:
DISPLAY OPTICAL FILTER AND DISPLAY HAVING THE SAME
Document Type and Number:
Japanese Patent JP2019056865
Kind Code:
A
Abstract:
To provide a display optical filter which offers not only good durability but also low light absorption (absorbance) in a wavelength range of 550-570 nm and good color reproducibility when used for displays.SOLUTION: A display optical filter includes an adhesive layer containing at least an adhesive resin having an acid value in a range of 0-20 mgKOH/g, a pigment 1 having an absorption maximum wavelength in a wavelength range of 480-510 nm and a full width at half maximum of 10-40 nm, and a pigment 2 having an absorption maximum wavelength in a wavelength range of 580-610 nm and a full with at half maximum of 10-30 nm. When a value of absorbance at the greatest one of the absorption maximum wavelengths of the pigment 1 and pigment 2 is normalized to 1, the absorbance in a wavelength range of 550-570 nm is 0.25 or less.SELECTED DRAWING: None
