1. A liquid-cooled liquid crystal panel comprising:
first and second substrates between which is held a liquid crystal material, said first substrate being a light emitting side
of the liquid crystal panel and the second substrate being a light entering side of the liquid crystal panel;
a first cover member attached to said first substrate, said first cover member comprising a first transparent substrate secured
over said first substrate and a first light transmitting window spaced from said transparent substrate, a first cavity capable
of containing cooling liquid being provided between said first transparent substrate and said first light transmitting window,
said first cover member further including a polarizing layer also spaced from said first transparent substrate;
a second cover member attached to said second substrate, said second cover member comprising a second transparent substrate
and a second light transmitting window spaced from said second transparent substrate, a second cavity capable of containing
cooling liquid being provided between said second transparent substrate and said second light transmitting window, said second
cover member further including a polarizing layer also spaced from said second transparent substrate; and
a cooling liquid filling said first and second cavities,
wherein,
said liquid crystal material and said cooling liquid are separated from each other, and
said polarizing layers are positioned between their respective light transmitting windows and their respective transparent
substrates.
