An in-plane switching mode LCD device, comprising:

• a substrate;
• gate and common electrodes on the substrate;
• a gate insulating layer on the substrate;
• a semiconductor layer on the gate insulating layer above the gate electrode;
• a data line having source and drain electrodes above both sides of the semiconductor layer;
• a passivation layer on the substrate including the data line;
• a pixel electrode on the passivation layer, the pixel electrode connected to the drain electrode via a first contact hole;
• and
• a dummy common electrode on the passivation layer at one side of the pixel electrode, the dummy common electrode connected to the common electrode via a second contact hole.

A method for manufacturing an in-plane switching mode LCD device, comprising:

• forming a gate line having a gate electrode and a common line having a common electrode on a substrate;
• forming a gate insulating layer on the substrate;
• forming a data line on the gate insulating layer substantially perpendicular to the gate line, the data line having source and drain electrodes;
• forming a passivation layer on the substrate including the data line;
• forming a pixel electrode on the passivation layer, the pixel electrode connected to the drain electrode;
• and
• forming a dummy common electrode on the passivation layer, the dummy common electrode connected to an outermost common electrode.
