The present invention provides a polymerizable compound with a structure of general formula I, which exhibits none or few of the problems existing in the prior art. A polymerizable liquid crystal composition comprising the polymerizable compound has good stability and higher reliability, and is embodied by having a smaller pretilt angle change and higher voltage holding ratio. Also, there is little or no image sticking effect in a liquid crystal display device comprising the polymerizable liquid crystal composition. The present invention also provides a method of synthesizing a polymerizable compound with a structure of general formula I. The present invention further provides a polymerizable liquid crystal composition comprising the polymerizable compound and a liquid crystal display device comprising the polymerizable liquid crystal composition. ##STR00001##
