Double-side liquid crystal display device and information appliance

An information appliance comprising:

• a first main body having operation switches;
• and
• a second main body having display means for visually displaying information, and coupled to the first main body for opening and closing, wherein
• the display means is 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 a passing a part of light from the front light passing through the liquid crystal material, and
• windows are disposed at an inner side of a casing and at an outer side of the casing when the second main body is closed, the front light is disposed at a first of the windows, and the second polarizing means is disposed at a second of the windows.
