Patent ID: 8212984

Claim:
A method of manufacturing an in-plane switching liquid crystal display device comprising: preparing the first and second substrates; forming a plurality of gate lines on the first substrate; forming an insulation film over a surface of the pixel area including the gate lines; forming the data lines and light shielding layers each having a predetermined width on the insulation film; forming a first protective film on the surface including the light shielding layers; forming a plurality of common electrodes on the first protective film; forming a second protective film on the surface including the common electrodes; forming a plurality of data electrodes on the second protective film, the data electrodes and the common electrodes to be alternately formed in each pixel area and having the same light transmitting area; and forming a liquid crystal layer between the first and second substrates, wherein each outer most common electrode of the plurality of common electrodes in the unit pixel is substantially vertically aligned with each of the light shielding layers and each of the data electrodes is formed in each area between two adjacent common electrodes.
