Liquid Crystal Barrier

A liquid crystal barrier, comprising:

• a barrier panel comprising:
• a lower substrate;
• an upper substrate opposite to the lower substrate;
• a plurality of first electrodes, opposite ends of each of which are connected to a respective one of a pair of first channel lines selected from among 2n (n being a natural number) first channel lines provided on edges of opposite sides of the lower substrate, wherein a first n of the of the 2n first channel lines are located on an edge of one side of the lower substrate and a second n of the of the 2n first channel lines are located on an edge of the other side of the lower substrate;
• a plurality of second electrodes, opposite ends of each of which are connected to a respective on of a pair of second channel lines selected from among 2n second channel lines provided on edges of opposite sides of the upper substrate, wherein a first n of the 2n second channel lines are located on an edge of one side of the upper substrate and a second n of the 2n second channel lines are located on an edge of the other side of the upper substrate;
• and
• a liquid crystal layer filled between the lower substrate and the upper substrate, and
• a driving voltage supply configured to supply a driving voltage or a common voltage to the first electrodes and the second electrodes, to supply the driving voltage to the first electrodes and the common voltage to the second electrodes, or to supply the driving voltage to the second electrodes and the common voltage to the first electrodes.
