Liquid crystal composition and use thereof

A liquid crystal composition, comprising:

• a polymerizable liquid crystal compound having a reverse wavelength dispersion property;
• and
• a non-liquid crystalline epoxy compound having two or more epoxy groups,
• wherein the non-liquid crystalline epoxy compound has no radical-curable functional group,
• wherein the non-liquid crystalline epoxy compound is one of the following Formula 7 or 8 and
• wherein after the liquid crystal composition is irradiated with ultraviolet rays of UVB region wavelengths at a light quantity of 100 mJ/cm2 to 250 mJ/cm2 in the total irradiance level and cured, and it has an in-plane retardation change rate represented by the following Equation 6 of 8% or less:
• wherein in Formula 7:
• X is an m-valent non-mesogenic saturated hydrocarbon group;
• n is an integer of 1 to 20;
• and
• m is an integer of 2 or more;
• and
• wherein in Formula 8:
• Y is an m-valent non-mesogenic hydrocarbon group;
• L9 is a single bond, —OCO—, —COO— or —O—;
• and
• m is an integer of 2 or more,
• wherein the non-mesogenic hydrocarbon group means a hydrocarbon group having no mesogen skeleton which means a structure containing at least two aromatic groups;
• ΔRin=(1−Rin2/Rin1)×100 [Equation 6]
• wherein ΔRin is an in-plane retardation change rate after high temperature storage, Rin1 is an initial in-plane retardation value, and Rin2 is an in-plane retardation value after high temperature storage at 80° C. for 96 hours.
