PURPOSE: An anti static multilayer anti reflection coating is provided to satisfactorily display an image by lowering the reflectance of right-side incident light and reverse-side incident light. CONSTITUTION: A reflection preventive member comprises a transparent substrate(2), a firsttransparent film(4), a first light absorptive film(5), a second transparent film(6), a second light absorptive film(7) and a third transparent film(8). The first transparent film is made of a transparent material and formed on the main surface of the transparent substrate. The thickness of the first transparent film is 50 nm or smaller. The first light absorptive film is made of a light absorptive material having conductivity and formed on the first transparent film. The first light absorptive film has a thickness of 30 nm adjusted according to a predetermined transmittance. The second transparent film is made of a transparent material and formed on the first light absorptive film. The second light absorptive film is made of a light absorptive material having conductivity and formed on the second transparent film. Moreover, the second light absorptive film has a thickness of 30 nm or smaller adjusted according to a predetermined transmittance. The third transparent film is made of a transparent material and formed on the light absorptive film. The optical thickness of the third transparent film is made to be about 1/4 of the wavelength when the frequency of incident light is about 550 nm. The refractive index of the third transparent film is lower than 1.52 which is lower than the refractive index of the first transparent film and that of the second transparent film. |
