Abstract
Disclosed is an LCD with improved image retention for increased reliability and screen quality. The LCD includes lower and upper substrates provided with predetermined patterns, respectively, and positioned to face each other with a predetermined distance; a liquid crystal layer interposed between the lower and upper substrates; and alignment layers positioned between the lower substrate and the liquid crystal layer and the upper substrate and the liquid crystal layer, respectively, to determine the initial arrangement of liquid crystals. The alignment layers have bubbles formed therein to reduce the capacitance generated by the alignment layers and the difference in level of the lower substrate for improved image retention.
