PURPOSE: To lower the reflectivity at the time of the dark display of a reflection type liquid crystal display device and to improve its contrast. CONSTITUTION: This reflection type liquid crystal display device is constituted by holding a GH liquid crystal layer 40 formed by adding dichromatic dyestuff to liquid crystals between a reflection electrode substrate 1 which is formed by successively laminating a reflection electrode 20 consisting of a metallic thin film having high reflectivity and an oriented film 30 consisting of polyimide, etc., in an insulating substrate 10, such as glass and a translucent electrode substrate 2 which is formed by successively laminating a light diffusion layer 70 consisting of randomly oriented LCP, a transparent electrode 60 consisting of a transparent conductive thin film of ITO, etc., and an oriented film 50 consisting of polyimide, etc., in a translucent insulating substrate 80, such as glass. The liquid crystal display device described above is so formed that the film thickness te of the transparent electrode 60 satisfies the relation te= (2m+1)λ/4}/ne±10[nm] (m=0, 1, 2,...) with respect to λ=550nm when the film thickness of the transparent electrode 60 is defined as te and the refractive index as ne. |
