Gas discharge display device

An optical film of an optical filter portion as a component of a gas discharge display device has an absorption region for selectively absorbing a light between 550 nm of wavelength and 620 nm of wavelength. A transmittance of an absorption peak within the absorption region is within a range of 20%...

Summary:An optical film of an optical filter portion as a component of a gas discharge display device has an absorption region for selectively absorbing a light between 550 nm of wavelength and 620 nm of wavelength. A transmittance of an absorption peak within the absorption region is within a range of 20% to 60% of an average transmittance in a visible light region.
