Abstract:
1. An array substrate for an in-plane switching liquid crystal display device, comprising: a substrate; a gate line and a data line on the substrate, the gate and data lines crossing each other to define a pixel region; a thin film transistor electrically connected to the gate and data lines; a common line parallel to the gate line; a passivation layer on the thin film transistor; a plurality of common electrodes formed on the passivation layer and perpendicularly connected to the common line, wherein each of the plurality of common electrodes adjacent the data line has a single flat plane overlapping the data line and a single first incline plane extending from the single flat plane; a plurality of pixel electrodes alternating with the plurality of common electrodes; and a plurality of passivation patterns extending from the passivation layer and located under the plurality of common electrodes, the plurality of passivation patterns having at least one second incline plane corresponding to the at least one first incline plane, wherein the at least one first incline plane slopes with an incline angle of about 45 degrees with respect to the substrate.
