Abstract
A liquid crystal barrier is configured to determine the viewing position of a viewer and selectively adjust based on the viewing position of the viewer. The liquid crystal barrier includes a barrier panel and a driving voltage supply unit. The barrier panel includes first electrodes, second electrodes, and liquid crystal layer. Opposite ends of the first electrodes are connected between 2n first channel lines, which form n channels, on a lower substrate. Opposite ends of the second electrodes are connected between 2n second channel lines, which form n channels, on an upper substrate. The liquid crystal layer is filled between the upper and lower substrates. The driving voltage supply unit is configured to supply at least one of a driving voltage and a common voltage to at least one of the first electrodes and the second electrodes.
