Filter für eine elektronische Anzeige und elektronische Anzeige-Vorrichtung unter Verwendung des Filters

摘要

A filter for an electronic display having at least one minimum value of transmittance in a visible light wavelength range of 400-700 nm, if transmittances (%) a, b and c at 435, 545 and 610 nm are compared, the difference between the maximum and minimum values of transmittance (%) is restricted to not more than 10, so that even if external light is a fluorescent lamp in which large emission peaks are present at 435, 545 and 610 nm, such as F10 and F6, the balance of the emission spectrum of the fluorescent lamp will not be lost due to the filter, thereby reducing unnatural coloring of the filter itself, which is installed at the front side of the electronic display, due to external light.
