An in-plane switching mode liquid crystal display (IPS-LCD) device. The device has a lower glass substrate and an upper glass substrate disposed parallel to each other. A plurality of transverse-extending scanning electrodes and a plurality of lengthwise-extending signal electrodes are patterned on the lower glass substrate to define a plurality of pixel areas. In each pixel area, at least one lengthwise-extending pixel electrode and at least two lengthwise-extending common electrodes are formed on the same level plane of the lower glass substrate, wherein the pixel electrode is disposed at the interval between the common electrodes. Also, a color resin layer is sandwiched between the signal electrodes and the common electrodes. Moreover, the common electrode is located over the signal electrode across two adjacent pixel areas.
