ABSTRACT:
A double-sided liquid crystal display device including a liquid crystal material, first and second electrodes for driving the liquid crystal material, first and second polarizers disposed on opposite sides of the liquid crystal material, a front light disposed at the opposite side of the first polarizer from the liquid crystal material, and a semitransmission reflector disposed at the same side of the liquid crystal material as the second polarizer for passing a part of light from the front light side passing through the liquid crystal. The first polarizer is disposed to absorb or transmit light passing through the liquid crystal material, and the second polarizer is disposed to absorb or transmit light passing through the liquid crystal material and then passing through the semitransmission reflector.
