PURPOSE:To obtain high display contrast by forming light absorptive films to the 1st and 2nd substrate sandwiching a liquid crystal. CONSTITUTION:An ITO (indium tin oxide) electrode 2, a cold mirror 3 which allows the transmission of IR rays and reflects visible light, the light absorptive film 4 manufactured of an IR absorptive dye having the max. absorption at 850nm wavelength and a liquid crystal orientation film 5 of SiO are successively laminated on the inside surface of the glass substrate 1 on the side where laser light is irradiated. On the other hand, an ITO electrode 9, the light absorptive film 8 manufactured of the IR absorptive dye and the liquid crystal orientation film 7 of SiO are successively formed on the inside surface of the glass substrate 10 and the side where the light is projected. Two sheets of such glass substrates 1, 10 are disposed to face each other via spacers 11 and 12 and the circumference is sealed by adhesive agents 13, 14. Normal octyl cyanobiphenyl 6 which is the crystal is injected into the spacing therebetween. The films 4, 8 are manufactured by dissolving the IR absorptive dye into acetone as a solvent, coating the soln. on the substrate by a spinner and allowing the acetone to evaporate thereafter.
