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.
