Description

technical field

[0001] The present invention relates to a polymerizable liquid crystal compound having polymerizability and liquid crystallinity, a composition containing the same, and a polymer obtained by using the composition. Materials for liquid crystal displays, especially polymerizable liquid crystal compounds for optical compensation films such as polarizers and retardation plates for liquid crystal displays, compositions containing them, and polymers obtained using these compounds. Background technique

[0002] In view of the improvement of display quality and weight reduction of liquid crystal display devices, the demand for polymer films whose internal molecular orientation structure is controlled is increasing as optical compensation films such as polarizing plates and retardation plates. In order to meet this demand, films utilizing the optical anisotropy possessed by polymerizable liquid crystal compounds are being developed.
