PURPOSE:To obtain high light absorptivity by setting the refractive index of a dielectric film at the intermediate value of the refractive index of electrodes and the refractive index of a light absorptive film. CONSTITUTION:An ITO electrode 15, a TiO2 dielectric film 16 formed by a resistance heating method, an Mo light absorptive film 17, an Al light reflecting film 18 and an SiO2 liquid crystal oriented film 19 are successively laminated on the inside surface of a glass substrate 14 on the side to be irradiated with laser light. On the other hand, an ITO electrode 22 and an SiO liquid crystal oriented film 21 are successively laminated on the inside surface of a glass substrate 23 on the projecting light side. Two sheets of the substrates 14, 23 are sealed at the peripheral via spacers 24, 25 by adhesive agents 26, 27 and a liquid crystal, i.e., normal octyl cyanobiphenyl 20 is injected into the space therebetween. The reflection at the boundary surface of the light absorptive film is decreased by providing the film 16 and the always higher light absorptivity than the light absorptivity obtd. with the film 17 along is obtd. Contrast is improved as well. |
