Patent ID: 8310644

Claim:
A method of fabricating an in-plane switching (IPS) mode liquid crystal display device, comprising: forming a gate electrode and a gate line on a first substrate; forming a gate insulation film on the first substrate including the gate electrode and the gate line; forming a semiconductor layer on the first substrate including the gate insulation film; forming a data line, a source electrode and a drain electrode on the first substrate including the semiconductor layer; forming a passivation film on the first substrate including the data line; forming a common electrode and a pixel electrode disposed alternately on the passivation film, at least one of the common electrode and the pixel electrode including a multi-layer having an opaque reflectance reducing layer and a transparent conductor layer on the opaque reflectance reducing layer; and attaching the first substrate to a second substrate, wherein the step of forming the common electrode and the pixel electrode includes: disposing the first substrate on a chuck; forming an opaque film on the passivation film; forming a conductive transparent film on the opaque film; etching the conductive transparent film to form the conductor layer; and etching the opaque film by using the conductor layer as a mask to form the opaque reflectance reducing layer, wherein a lower surface of the opaque reflectance reducing layer is directly contacted with the passivation film and an upper surface of the opaque reflectance reducing layer is directly contacted with a lower surface of the transparent conductor layer to block a light reflected from the chuck disposed at a lower portion of the common electrode and the pixel electrode, wherein the opaque film is over-etched by using the conductor layer as a mask.
