Abstract
A liquid crystal composition including a liquid crystal compound capable of expressing a birefringence with reverse wavelength distribution, a (meth)acrylic acid ester compound other than the liquid crystal compound, and a surfactant containing a fluorine atom, wherein a ratio Mw/Np of a molecular weight Mw of the (meth)acrylic acid ester compound relative to a number of π electrons Np of the (meth)acrylic acid ester compound is 17 or more and 70 or less, and an amount of the surfactant relative to 100 parts by weight of a total of the liquid crystal compound and the (meth)acrylic acid ester compound is 0.11 part by weight or more and 0.29 part by weight or less.

A liquid crystal composition comprising a liquid crystal compound capable of expressing a birefringence with reverse wavelength distribution, a (meth)acrylic acid ester compound other than the liquid crystal compound, and a surfactant containing a fluorine atom, wherein
- a ratio Mw/Np of a molecular weight Mw of the (meth)acrylic acid ester compound relative to a number of π electrons Np of the (meth)acrylic acid ester compound is 17 or more and 70 or less, and
- an amount of the surfactant relative to 100 parts by weight of a total of the liquid crystal compound and the (meth)acrylic acid ester compound is 0.11 part by weight or more and 0.29 part by weight or less.
A liquid crystal cured film comprising a liquid crystal cured layer formed of a cured product of a liquid crystal composition containing a liquid crystal compound, wherein
- the liquid crystal cured layer includes a first layer, a second layer, and a third layer which are disposed in this order and contain the liquid crystal compound which may be in a fixed orientation state,
- first tilt angle formed by molecules of the liquid crystal compound contained in the first layer relative to a layer plane is constant in the first layer,
- second tilt angle formed by molecules of the liquid crystal compound contained in the second layer relative to a layer plane is constant in the second layer,
- the second tilt angle is discontinuously different from the first tilt angle,
- third tilt angle formed by molecules of the liquid crystal compound contained in the third layer relative to a layer plane is constant in the third layer, and
- the third tilt angle is discontinuously different from the first tilt angle and the second tilt angle.
