A spin crossover liquid crystal polymer comprising an Fe(II) complex is provided to obtain a liquid crystal material showing a liquid crystal phase transition simultaneously with a spin transition and useful for fabricating display devices. A spin crossover liquid crystal polymer comprises: a liquid crystal polymer containing repeating units represented by the following formula 1; and 20-50 wt% of an Fe(II) complex represented by the following formula 2. In formula 1, n is an integer of 5-200, and m is an integer of 6-20. In formula 2, R is -C18H37 or -(CH2)2OH, and Anion is any one selected from the group consisting of p-toluenesulfonate, 3-nitrophenyl sulfonate, ClO4-, BF4- and Br-.
