Patent ID: 8446553

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 substrates; forming an insulation film over an entire surface of the first substrate including the gate lines; forming a plurality of 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 data lines and the shielding layer; alternately forming common electrodes and data electrodes on the first 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 outmost common electrode of the plurality of common electrodes in the unit pixel is substantially vertically aligned with the light shielding layers and each of the data electrodes is formed in each area between two adjacent common electrodes.
