Abstract
Provided are a reactive mesogen that may improve display quality of a liquid crystal display, and a liquid crystal composition including the same. The reactive mesogen is represented by the following Formula: BZ1b1XZ2b2Pa where X, Z1, Z2, B, and Pa are specified in the disclosure, and each of b1 and b2 is independently an integer between 0 to 6, inclusive.
