METHOD FOR MANUFACTURING AN FFS MODE LCD TO REDUCE THE NUMBER OF MASKS AND INCREASE RESPONSE SPEED OF LIQUID CRYSTAL MATERIAL

摘要

PURPOSE: A method for manufacturing an FFS(Fringe Field Switching) mode LCD(Liquid Crystal Display) is provided to skip the manufacturing process for patterning a common electrode so as to reduce the number of masks and manufacturing processes, and make it possible to form vertical electric field and horizontal electric field in a liquid crystal layer so as to increase response speed of liquid crystal material, by forming the common electrode having wedge shaped slits not on a lower substrate but on an upper substrate. CONSTITUTION: A pixel electrode(29) of comb configuration is formed over a lower substrate(20). The pixel electrode has wedge shaped slits(29a). A common electrode(33) of comb configuration is formed over an upper substrate. The common electrode has wedge shaped slits(33a). The wedge shaped slits of the common electrode are disposed between the wedge shaped slits of the pixel electrode. Liquid crystals are injected between the lower and the upper substrates. When voltage is applied between the common electrode and the pixel electrode, vertical electric field and horizontal electric field are formed in a liquid crystal layer, thus increasing response speed of liquid crystal material.
