[Problem] To provide an optical element that can improve off-axis color shift when incorporated in a liquid crystal display device, a production method for the optical element, and a liquid crystal display device. [Solution] An optical element that is equipped with a reflective polarizer to which a cholesteric liquid crystal phase comprising a discotic liquid crystal compound is fixed. In the reflective polarizer, at ±50 nm outside the central reflection wavelength, the head-on retardation value Re is 0 nm ≤ Re < 10 nm, and the absolute value | Ret(50°) | of the retardation value Ret in the direction of a polar angle of 50° is | Ret(50°) | ≤ 50 nm. |
