Liquid crystal display using compensating film and manufacturing method thereof

A liquid crystal display comprising:

• a liquid crystal panel having an upper substrate, a lower substrate facing the upper substrate and spaced apart by a predetermined distance from the upper substrate, and a liquid crystal layer interposed between the upper substrate and the lower substrate;
• first compensating films respectively formed over an inner surface of the upper substrate and an inner surface of the lower substrate;
• second compensating films respectively attached over an outer surface of the upper substrate and an outer surface of the lower substrate;
• and
• first and second polarizing plates attached over the second compensating films such that a first optical transmission axis of the first polarizing plate is perpendicular to a second optical transmission axis of the second polarizing plate.
