Abstract
An in-plane switching liquid crystal display having a plurality of protrude electrodes of a special shape is disclosed. Each of the protrusion electrodes has a protrusion body with a surface coated with an electrically conductive material. The protrusion body has flat side located on the lower substrate of the liquid crystal display, defining the basewidth of the protrusion electrodes. The protrusion body has a top portion with a round head and a bottom portion with a waist portion, smaller than the basewidth. It has been found that, the round head of the top portion and the waist portion of the bottom portion can improve the efficiency of the optical transmissivity of the liquid crystal layer as well the contrast between the bright state and the dark state of the display.
