Disclosed is an in-plane switching active matrix type liquid crystal display with greater improvements on color shifting and contrast. The liquid crystal display comprises an in-plane switching type liquid crystal display panel having an active device substrate, an opposing substrate and a liquid crystal layer held sandwiched between the active device substrate and the opposing substrate, a first polarizer laid out on one side of the liquid crystal display panel, a second polarizer laid out on the opposite side of the liquid crystal display panel, first to third optical compensators placed in order between the liquid crystal display panel and the first polarizer, and a fourth optical compensator placed between the liquid crystal display panel and the second polarizer. As the first to fourth optical compensators are provided to compensate for retardation of the liquid crystal layer and retardation of the polarizers, black stretching does not occur even when observation is made from any viewing angle, and a reduction in contrast does not occur. Nor does color shifting occur at the time of displaying black.
