<P>PROBLEM TO BE SOLVED: To provide a lateral electric field mode liquid crystal display device and a manufacturing method thereof that reduce light leakages due to level differences at electrode edge parts by after-treating the entire surface of a substrate or the level difference portions by using a UV-irradiation or ion-beam irradiation method as a non-rubbing system after rubbing the entire surface of the substrate. <P>SOLUTION: The lateral electric field mode liquid crystal display device includes first and second substrate, gate and data lines that perpendicularly cross each other on the first substrate to define a pixel region, a thin film transistor at a crossing of the gate and data lines, a pixel electrode and a common electrode alternately formed in the pixel region and spaced apart from each other by a prescribed distance, an alignment film on the entire surface of the substrate, wherein, at least one of the gate line, the data line, the pixel electrode, and the common electrode has a level difference portion with a difference of about 0.1 μm or greater, the alignment film is primarily aligned, and at least a portion of the primarily-aligned alignment layer around the level difference portion is secondarily aligned, and a liquid crystal layer between the first and the second substrates. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
