PURPOSE: A subphthalocyanine compound, a disc shaped liquid crystal compound, which shows liquid crystal property at room temperature and luminescence property, its preparation method and display element using the compound as a liquid crystal layer forming material or a color development material is provided. CONSTITUTION: The subphthalocyanine compound has a structure of formula I, wherein Ris alkyl group having 1-30 number of carbon, aliphatic cyclic hydrocarbons having a 5-20 number of carbon, or aromatic hydrocarbons having 6-30 number of carbon; X means halogen atom; and B means either boron(B) or aluminum(Al). Since the compound has liquid crystal at room temperature and luminescence property, it can be advantageously used for a display element such as a liquid crystal display element, an organic electroluminescence and the like. The preparation method for the compound includes reacting 1,2-dihalogen 4,5-dicyanobenzene with a thiol compound in the presence of a base to obtain 1,2-dialkylthio-4,5-dicyanobenzene, and conducting ring condensation step.
