Abstract
The present invention provides to a front panel for a display in which the light transmittance of the front panel at a wavelength of 450 nm is higher than the light transmittance at a wavelength of 525 nm and the light transmittance at the wavelength of 525 nm is higher than the light transmittance at a wavelength of 630 nm. The front panel for a display of the present invention improves image contrast and color reproducibility of the display, when it is installed at the front side of a projection television receiver, a liquid crystal display, a plasma display, or the like.
