ABSTRACT:
The present invention provides an in-plane switching liquid crystal display (IPS-LCD) device that includes a substrate, a protrusive layer having many protrusions on the substrate and a transparent electrode on each of the protrusions. One may dispose a color filter on the protrusions and fill in liquid crystal material between the color filter and the substrate. In contrast to conventional IPS-LCD devices, the IPS-LCD device of the present invention does not require the use of spacers. The present invention may thus largely enhance the light penetration rate and simplify the manufacturing process.
