Abstract
Disclosed is an in-plane switching(IPS) mode liquid crystal display(LCD) to prevent generating parasitic electric field due to residual DC components and static electricity. The IPS mode LCD according to the present invention comprises a first substrate; counter electrodes formed on the first substrate; pixel electrodes formed on the first substrate and spaced apart from the counter electrodes; a first high dielectric layer formed between the counter and pixel electrodes on the first substrate in which the counter and pixel electrodes are formed; a second substrate opposed to the first substrate; and a second high dielectric layer disposed at an inner surface of the second substrate.
