A liquid crystal display device with an IPS mode having wide view angle characteristic and capable of improving response time and transmittance, is disclosed. A liquid crystal display device with an in-plane switching mode includes a first substrate having first and second electrodes formed thereon. A second substrate is disposed opposite to the first substrate with a selected distance. On a surface of the second substrate are also formed third and fourth electrodes. When a voltage is applied to the respective electrodes, a first electric field which is parallel to the planes of the substrates is generated between the first electrode and the second electrode, and a second electric field which is parallel to the planes of the substrates and is orthogonal to the first electric field is generated between the third electrode and the fourth electrode. A polarizer is arranged on the outside of the first substrate and a analyzer is arranged on the outside of the second substrate. A first homogeneous alignment film is applied to the first substrate on which the first and second electrodes are formed. A second homogeneous alignment film is also applied to the second substrate on which the third and fourth electrodes are formed. A liquid crystal layer having liquid crystal molecules is interposed between the both substrates, wherein the liquid crystal molecules are arranged in a homogeneous state in an absence of the electric field and are twisted in a presence of the electric field.

The pixel electrode and the counter electrode are devised so that an electric field generated between the counter electrode and the pixel electrode in one unit pixel region is parallel to the gate bus line and an electric field in another unit pixel regions adjacent to the one unit pixel region in left, right, upper and lower directions is vertical to the gate bus line. Therefore, the color shift of the liquid crystal display can be prevented.
