<p>An electronic display-use filter having the minimal value of at least one transmittance in a visible light area with a wavelength of 400 nm-700 nm, wherein transmittances (%) a, b, c at 435 nm, 545 nm, 610 nm are compared and the difference between a maximum value and a minimum value of these transmittances (%) is restricted to within 10 to thereby reduce the unnatural coloring by an external light of the filter itself installed in front of an electronic display, with the balance of the emission spectrum of a fluorescent lamp not affected by the filter even if a fluorescent lamp such as F10 and F6 where large light emission peaks are present at 435 nm, 545 nm, 610 nm is used as an external light.</p> |
