Abstract

There is provided an integrated wide viewing film including: a first film having an optical axis located in-plan; and a second film having an optical axis located in a thickness direction thereof, and inclined at a predetermined angle in an in-plane direction. The IPS-LCD employing the integrated wide viewing film can be significantly improved in a contrast ratio in a diagonal direction.
