A display panel includes a face plate having a transparent substrate, a plurality of phosphor layers disposed on the transparent substrate for emitting different color lights, and a plurality of transmittance adjustment layers interposed between the transparent substrate and the plurality of phosphor layers. Each transmittance adjustment layer corresponds to each phosphor layer for adjusting the transmittances of the lights emitted from the plurality of phosphor layers, and the transmittance adjustment layers have a filtering function with an approximately constant transmittance in the visible light wavelength region. In addition, a rear plate has a plurality of display elements each corresponding to each phosphor layer, wherein the face plate and the rear plate are disposed so that the phosphor layers formed on the face plate are opposite to the display elements formed on the rear plate.

Face panel for color image display apparatus, panel for color image display apparatus, and color image display apparatus

A face panel for a color image display apparatus includes a transparent substrate, a plurality of phosphor layers disposed on the transparent substrate for emitting different color lights, and a plurality of transmittance adjustment layers interposed between the transparent substrate and the plurality of phosphor layers in correspondence to the plurality of phosphor layers, respectively, for adjusting the transmittances of the lights emitted from the plurality of phosphor layers. The transmittance adjustment layer has a filtering function having an approximately constant transmittance in the visible light wavelength region, and the transmittances of the plurality of transmittance adjustment layers are set to different values to the respective colors of the phosphor layers corresponding thereto.
