Provided is a curved display device capable of preventing or reducing local light leakage while achieving a certain contrast ratio. The curved display device includes a liquid crystal panel in a normally black mode. The liquid crystal panel includes a first polarizer, a liquid crystal cell, and a second polarizer in a stated order from a viewing surface side. The liquid crystal cell includes a first substrate including a transparent substrate, a liquid crystal layer, and a second substrate including a transparent substrate in a stated order from the viewing surface side. At least one of the first substrate or the second substrate is provided with a third polarizer on a surface of the transparent substrate closer to the liquid crystal layer.
