Title:
FLAT-TYPE IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/049589
Kind Code:
A1
Abstract:
This invention provides a flat-type image display device comprising a front
substrate having a fluorescent substance screen provided on the inner surface
of a transparent substrate and a backside substrate that comprises a plurality
of electron release elements and is disposed opposite to the front substrate.
An impact absorbing layer composed mainly of a polymer having a durometer A hardness
of 20 to 60 is provided on the outer surface of the front substrate, and a light antireflection
layer is provided on the impact absorbing layer. A transparent silicone polymer
having a total light transmittance of not less than 90% may be mentioned as the
polymer constituting the impact absorbing layer. The impact absorbing layer
may contain 0.0005 to 0.005% by weight of a dye. Preferably, a urethane polymer
having good restoring force is used as a base material for the light antireflection
layer. The flat-type image display device is advantageous in that the effect
of preventing damage to a front substrate upon external impact is high, is less
likely to cause the exposure of a double image upon external light reflection,
and, further, images having high quality can be produced in a light weight at low
cost.
