Abstract
In a flat display device having a pair of substrates for defining a gas discharge space in which a gas used to generate discharge luminance is sealed, means for absorbing or reflecting near infrared rays is included.
Claims16
A flat display device, comprising:
- a pair of substrates defining therebetween a gas discharge space in which a gas used to generate discharges is sealed;
- and
- a fluorescent layer between the pair of substrates irradiated with ultraviolet rays to emit visible rays;
- and
- a film associated with the flat display device to absorb or reflect near infrared rays.

A flat display device, comprising:
- a pair of substrates configured to define a gas discharge space in which a gas used to generate discharge is sealed;
- a fluorescent layer between the pair of substrates irradiated with ultraviolet rays to emit visible rays;
- and
- a film configured to absorb or reflect near infrared wavelengths in the range of 820 nm to 880 nm.
1 more element
A flat display device comprising:
- a pair of substrates configured to define a gas discharge space in which a gas used to generate discharge is sealed, and
- a near infrared absorbent consisting of dye, which is added to material for either a first substrate of the pair of substrates, a protection plate arranged in spaced relationship with the pair of substrates, or a dielectric film covering a display electrode pair which is provided on the first substrate.
