ABSTRACT:
A liquid crystal display device includes a viewing side circularly polarizing member provided outside the viewing side substrate. The viewing side circularly polarizing member includes a linearly polarizing plate and a retardation plate. The absorption axis of the linearly polarizing plate is at an angle θ1of −25° and the slow axis of the retardation plate being at an angle θ2of +20° with respect to a 0° horizontal direction of the viewing side circularly polarizing member in plan view assuming the counterclockwise rotation in plan view is positive.
