Abstract
A 3D image display device includes a display panel, a barrier, a controller, and a barrier driver. The barrier includes: 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 first electrodes; 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 third electrodes; and a liquid crystal layer disposed between the first and second substrates. The barrier driver receives a barrier control signal from the controller, and applies a reference voltage to the first electrodes, the second electrodes, the third electrodes, and/or the fourth electrodes, and applies a liquid crystal driving voltage to one or more other ones of the first to fourth electrodes.
