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.

Liquid crystal barrier

A stereoscopic image display device includes a substrate; a plurality of black matrices formed parallel to one another on a first surface of the substrate; a plurality of black stripes formed on a second surface of the substrate opposite the first surface, each of the plurality of black stripes corresponding to one of the plurality of black matrices, each of the plurality of black stripes having a width equal to or greater than a width of the corresponding one of the plurality of black matrices; and a patterned retarder film formed on the plurality of black stripes, the patterned retarder film including a plurality of first retarder patterns and a plurality of second retarder patterns, wherein a first retarder pattern is disposed over a region between a first pair of black stripes, and a second retarder pattern is disposed over a region between a second pair of black stripes that is adjacent to the first pair of black stripes, and wherein the width of each of the plurality of black stripes is less than or equal to twice an adhesion margin of the patterned retarder film.
