Abstract: Provided is an optical element including, sequentially from a viewing surface side toward a back surface side: a first polarizer; a negative C plate; a phase difference layer; and a second polarizer. A transmission axis of the first polarizer is parallel to a transmission axis of the second polarizer. The phase difference layer contains anisotropic molecules. In the phase difference layer, a tilt angle of the anisotropic molecules on a viewing surface side in the phase difference layer and a tilt angle of the anisotropic molecules on a back surface side in the phase difference layer are the same as each other and greater than 0°. A slow axis of the phase difference layer, in a case of lying in a tilt direction of the anisotropic molecules, is parallel to or perpendicular to the transmission axis of the first polarizer.
