Gasentladungs-Anzeigevorrichtung |
摘要 |
A gas-discharge display apparatus (100)is provided that reduces influence of light emission of the discharging gas so as to enhance a color reproducible range and make color purity of red color close to the ideal value. The apparatus uses a gas containing at least one of neon and helium for generating the gas discharge and exciting three kinds of fluorescent materials having different light colors to emit light for color image display. In front of the gas discharge space, an optical filter (60)is disposed, whose transmittance at the wavelength of 585 nanometers is smaller than both the transmittance at the wavelength of 450 nanometers and the transmittance at the wavelength of 620 nanometers. <IMAGE> |
