Abstract
An in-plane switching liquid crystal display has a plurality of protrusion electrodes. Each of the protrusion electrodes has a protrusion body with a surface coated with an electrically conductive layer made from a metal oxide. An adhesion-enhancement medium is provided between the electrically conductive layer and the surface of the protrusion body. The adhesion-enhancement medium comprises a metal such as aluminum or molybdenum or a metal alloy containing molybdenum and at least one of niobium, tantalum, titanium, zirconium, tungsten, aluminum and nitride or a metal alloy containing aluminum and at least one of niobium, tantalum, titanium, zirconium, tungsten, molybdenun and nitride. The protrusion body can have the shape of a rectangle, triangle, bell, rectangle with a round top, or a cross sectional area having a top portion with a round or flat head and a bottom portion with a waist portion, smaller than the basewidth.
