Patent ID: 7002649

Claim:
A double-side liquid crystal display device comprising: a liquid crystal material, first and second electrodes for driving the liquid crystal material, first and second polarizing means disposed on opposite sides of the liquid crystal material, a front light disposed on the opposite side of the first polarizing means from the liquid crystal material, and semitransmission reflecting means disposed on the same side of the liquid crystal material as the second polarizing means, for passing a part of light from the front light passing through the liquid crystal material, wherein the semitransmission reflecting means is a reflector, disposed between the liquid crystal material and the second polarizing means, having a transmission window for passing the part of light from the front light passing through the liquid crystal material, the first polarizing means is optically disposed to absorb or transmit light passing through the liquid crystal material, and the second polarizing means is optically disposed to absorb or transmit light passing through the liquid crystal material and then passing through the semitransmission reflecting means.
