Abstract: The present invention relates to polymerizable mesogens which does not need a photoinitiator and a polymerizable liquid crystal composition and, more specifically, a polymerizable mesogen compound in the present invention has: improved photoreaction efficiency with relatively low energy by introducing methoxyacrylate as a photoreactive group; high solubility in host liquid crystal due to an asymmetrical structure; and an effect in improving the stability of pretilt angle after photocrosslinking, thereby being used as a polymerizable liquid crystal composition, particularly, a polymerizable liquid crystal composition for polymer stabilizing orientation type liquid crystal display.
