First and second alignment layers have characteristics to allow LC in a transmission region can be aligned in the same direction as a transmission axis of a lower polarizer. A third alignment layer is aligned so that the LC in the reflection region can be twisted from a lower side to an upper side with a predetermined twisted angle (?). Here, the twisted angle (?) of the LC in the reflection region, and an angle (?) between an alignment direction of an uppermost LC in the reflection region and the transmission axis of the upper polarizer are set so that optical reflectivity in the reflection region is ‘0’ when the LC is not driven.
