ABSTRACT:
To achieve an expansion of color reproducibility and an improvement in contrast ratio, color filters 8R, 8G and 8B formed in stripes are successively arranged on one surface of a front glass substrate 1, interposing a black matrixes 7 between them. Sustaining electrodes 6 are provided thereon and a dielectric layer 9 and a protecting layer 10 are provided. On a rear glass substrate 2, barrier ribs 3 are provided in the manner they face the respective black matrixes 7, and thus the spaces between the barrier ribs 3 facing the respective color filters 8R, 8G and 8B form cells. The cells are respectively provided with the sustaining electrodes 6 falling at right angles with the address electrodes 4, coated with fluorescent substances 5R, 5G and 5B corresponding to the respective colors, and also sealed to hold discharge gas therein. A wave band selecting filter 11 for screening the light emitted from the discharge gas in the respective cells is provided on the other surface of the front glass substrate 1.
