Liquid crystal composition, method for producing retardation layer, and circularly polarizing plate

A liquid crystal composition comprising:

• a polymerizable liquid crystal compound capable of expressing birefringence with inverse wavelength dispersion;
• a surfactant containing a fluorine atom;
• and
• a solvent, wherein
• the surfactant contains a fluorine atom at a ratio of 25% by weight or less in a molecule of the surfactant,
• the ratio of the fluorine atom in the molecule of the surfactant is measured by a method comprising steps of:
• combusting the surfactant to generate a gas;
• absorbing the gas into a solution to obtain an absorbing liquid;
• and
• analyzing a part of the absorbing liquid by ion chromatography to measure the ratio of the fluorine atom in the molecule of the surfactant.
