FILTER FOR ELECTRONIC DISPLAY AND ELECTRONIC DISPLAY DEVICE

PROBLEM TO BE SOLVED: To provide a filter for an electronic display that strikes a balance between the improvement in display contrast under the irradiation of a three-wavelength region emission fluorescent lamp and the inhibition with an unnatural color of the filter itself. SOLUTION: The light transmittance Y4 % in a green emission peak wavelength of an electronic display being an installation object is arranged such that the light transmittance Y2 % in the green emission peak wavelength of the three-wavelength region emission fluorescent lamp is low ≥5, and the absolute value of Tg-0.3Tb-0.7Tris ≤10 which is calculated from the average transmittance Tg% in the range of ±15nm centering on the green emission peak wavelength of the three-wavelength region emission fluorescent lamp, the average transmittance Tb% in the range of ±15nm centering on the blue emission peak wavelength of the three-wavelength region emission fluorescent lamp, and the average transmittance Tr% in the range of ±15nm centering on the red emission peak wavelength of the three-wavelength region emission fluorescent lamp.
