<P>PROBLEM TO BE SOLVED: To provide a filter for a display for making it compatible to secure screen brightness by improving contrast of the display by regulation of reflectance and transmittance in RGB emission wavelength of a three-wavelength region emission fluorescent lamp and further regulation of average transmittance in the filter for the display installed on the front face of the electronic display. <P>SOLUTION: In the filter for the display in which an average reflectance Rg(%) of a range of ±15 nm by centering green emission peak wavelength of the three-wavelength region emission fluorescent lamp, average reflectance Rb(%) of a range of ±15 nm by centering blue emission peak wavelength of the three-wavelength region emission fluorescent lamp and average reflectance Rr(%) of a range of ±15 nm by centering red emission peak wavelength of the three-wavelength region emission fluorescent lamp are 3.5% or less, luminous transmittance (Y) is in the range of 20-50%. <P>COPYRIGHT: (C)2007,JPO&INPIT |
