GAS DISCHARGE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To enhance color reproducibility by lessening the influence of the light emission of discharge gas. SOLUTION: The gas discharge display device which reproduces the colors of respective pixels of color images by controlling the light emission quantities of three kinds of cells varying in light emission colors is arranged with filters of spectral characteristics which set the mixed colors of the light emission colors of three kinds of the cells when reproducing white at the colors indicated by chromaticity coordinates giving rise to deviation to black body loci in a chromaticity diagram and change the mixed colors to the colors which are higher in the color temperature than the color temperature of the mixed colors and are indicated by the chromaticity coordinates approximate to the black body loci on the front side of three kinds of the cells.
