We have prepared colorants-containing polymethyl methacrylate (PMMA) films for the front filter of plasma display panel (PDP) by solvent casting method and investigated their optical properties. In this study, a cyanine dye and a Cu-hydrate pigment have been used as the colorants for neon-cutting and color control, respectively. The experimental results have revealed that PMMA films act as a band rejection-type color filter indicating characteristics of sharp absorptions in specific regions. In the PDP devices with our band rejection color filters, the luminance from unnecessary emissive light is sufficiently reduced, resulting in wider color gamut and higher color purity.
