An in-plane switching mode liquid crystal display device includes first and second substrates facing each other, a gate line and a data line arranged on the first substrate crossing each other and defining a pixel region, a switching device at a crossing of the gate line and the data line, a common electrode and a pixel electrode alternately disposed in the pixel region, at least one of the common electrode and the pixel electrode including a multi-layer having a conductor layer and a reflectance reducing layer, and a liquid crystal layer formed between the first and second substrates.
