<p>The present invention discloses a liquid crystal display device. More particularly, the invention relates to a liquid crystal display device including a test circuit of a structure in which two pixels share one data line like a liquid crystal display device of a Z-inversion type or column inversion structure. The liquid crystal display device according to an embodiment of the invention includes a liquid crystal panel in which a plurality of gate wires and data wires intersect with each other and a plurality of pixels are defined on the intersected part, a gate operating part included in its side and outputting a gate operating signal to the gate wires, a data operating part outputting a data signal to the data wires, and a test circuit part formed between the gate wires and the gate operating part and outputting the gate operating signal by alternating it at 1/2 frame by odd nth or even nth gate wire unit in response to a test control signal during a test mode. According to an embodiment, a gate operating signal between the gate operating part and the pixel area is divided into odd numbers or even numbers in order to operate only a pixel corresponding to a color to be tested through the test circuit. Therefore, a test process of the pixel is normally performed in the liquid crystal display device of the column inversion structure.
