A dual liquid crystal barrier includes a first substrate having space-division electrodes, the space-division electrodes including first electrodes and second electrodes, a second substrate having time-division electrodes, the time-division electrodes including third electrodes and fourth electrodes, and a liquid crystal layer between the first substrate and the second substrate. The dual liquid crystal barrier is configured to selectively operate as a space-division liquid crystal barrier based on the space-division electrodes, or a time-division liquid crystal barrier based on the time-division electrodes.
