Abstract:
1. A 3D image display device comprising: a display panel for displaying an image corresponding to an input video signal; a barrier arranged in correspondence to the display panel, the barrier comprising a first substrate, a plurality of first electrodes disposed on the first substrate and extended in a first direction, a plurality of second electrodes respectively disposed between adjacent ones of the first electrodes on the first substrate, a second substrate opposing the first substrate, a plurality of third electrodes disposed on the second substrate and extended in a second direction crossing the first direction, a plurality of fourth electrodes respectively disposed between adjacent ones of the third electrodes on the second substrate, and a liquid crystal layer disposed between the first substrate and the second substrate; a controller for generating a barrier control signal for determining a pattern of the barrier; and a barrier driver for applying, based on the barrier control signal, a reference voltage to the first electrodes, the second electrodes, the third electrodes and/or the fourth electrodes, and for applying a liquid crystal driving voltage to the first electrodes, the second electrodes, the third electrodes and/or the fourth electrodes to which the reference voltage is not applied.
