A method for manufacturing alignment films of liquid crystal panel includes the steps of: injecting a liquid crystal mixture containing liquid crystal molecules and liquid crystal reactive monomers to form a liquid crystal cell; placing the liquid crystal cell in a first reaction machine to subject the same to a voltage, ultraviolet radiation, and a temperature, so that the liquid crystal reactive monomers produce a polymerization reaction; moving the liquid crystal cell to a second reaction machine after a first preset time period in order to subject the same to a voltage and a temperature to continue the polymerization reaction, and forming alignment films on inner surfaces of a first substrate and a second substrate, respectively.
