Claim:
A barrier panel device for 3D image reproduction, the barrier panel device comprising: a barrier panel, which comprises: a first electrode comprising a plurality of segments arranged substantially parallel and adjacent to each other, a second electrode comprising a plurality of barriers arranged substantially parallel to each other and substantially perpendicular to the plurality of segments, wherein the plurality of barriers comprises odd barriers and even barriers arranged between adjacent ones of the odd barriers, and a liquid crystal disposed between the first electrode and the second electrode; a segment driving voltage controller, which controls on/off states of segment driving voltages applied to the plurality of segments; and a barrier driving voltage controller, which alternatively and repeatedly applies a barrier driving voltage to the odd barriers, while applying 0V to the even barriers, and applies the barrier driving voltage to the even barriers, while applying 0V to the odd barriers, wherein the on/off states of the segment driving voltages alternate while the on/off states of the barrier driving voltages alternate, and the segment driving voltage controller controls each segment driving voltage to be periodically applied to a corresponding segment, controls a time of changing the on state of the segment driving voltage of predetermined segments to be sequentially delayed from a time of changing the on state of a segment driving voltage of a corresponding adjacent neighboring segment, and controls a time of changing the off state of the segment driving voltage of the predetermined segments to be sequentially delayed from a time of changing the off state of the segment driving voltage of the corresponding adjacent neighboring segment.
