Liquid crystal element and head-mounted display

A liquid crystal element comprising:

• a first substrate, a first weak anchoring horizontal alignment film, a liquid crystal layer containing dual-frequency drive liquid crystal molecules, a second weak anchoring horizontal alignment film, and a second substrate in this order,
• wherein the liquid crystal element further includes a retardation layer on at least one of a side of the first substrate opposite to the liquid crystal layer or a side of the second substrate opposite to the liquid crystal layer,
• a comb-teeth electrode configured to generate an electric field for the liquid crystal layer is provided on at least one of the first substrate or the second substrate,
• the dual-frequency drive liquid crystal molecules are twist-aligned between the first substrate and the second substrate in a voltage applied state and a voltage non-applied state, and a twist direction in the voltage applied state is identical to a twist direction in the voltage non-applied state,
• an alignment direction of dual-frequency drive liquid crystal molecules located at a center of the liquid crystal layer in a thickness direction is perpendicular or parallel to an extension direction of the comb-teeth electrode,
• the retardation layer includes a first quarter-wavelength film and a second quarter-wavelength film in this order from a side closer to the liquid crystal layer, and
• at least one of the first quarter-wavelength film or the second quarter-wavelength film is a positive A plate or a negative A plate.
