Abstract

The present invention discloses a coupled polarizing plate set comprising a first coupled polarizing plate and a second coupled polarizing plate where compensation films having specific optical properties are laminated and a liquid crystal display capable of be easily mass-producing the coupled polarizing plate while ensuring a wide viewing angle equal to or more than the known other liquid crystal mode by adopting the coupled polarizing plate set to a blue phase liquid crystal mode.
