Abstract
A time-division liquid crystal barrier includes an upper substrate having first electrodes, second electrodes, and a first insulation layer between the first and second electrodes, the first electrodes being arranged with a first gap, and the second electrodes being arranged with a second gap, a lower substrate having third electrodes, fourth electrodes, and a second insulation layer between the third and fourth electrodes, the third electrodes being arranged with the first gap, and the fourth electrodes being arranged with the second gap, and a liquid crystal layer between the upper substrate and the lower substrate, the first and second electrodes being alternately arranged with respect to the first insulation layer, the third and fourth electrodes being alternately arranged with respect to the second insulation layer, the first electrodes overlap the third electrodes, and the second electrodes overlap the fourth electrodes.
