Creation-annihilation process of defects in WD rolls of a nematic liquid crystal was studied experimentally as an electrohydrodynamic instability of a layer within two free lateral side-walls of relatively large aspect ratio. A regular pattern was seen to be formed through creation and annihilation of defects. The defects began to move fast as they approach to the side-walls. Their motion changed from gliding (across roll-axis) one to climbing (along roll-axis) one with time. Finally the defects disappeared through climbing motion.
