PROBLEM TO BE SOLVED: To improve brightness on a display surface by providing an isotropic diffusion layer on an opposite surface of one side substrate of a pair of transparent substrates opposite to each other and providing a reflection plate turning its rugged surface to the substrate side outward the other side substrate. SOLUTION: A dielectric anisotropic liquid crystal layer 3 containing a two color property dystuff molecule 4 is arranged between a pair of glass substrates 1, 2 opposite to each other. The isotropic diffusion layer 5 is provided on the bottom surface of the upward glass substrate 1. A 1/4λ plate 10 is provided on the bottom surface of the downward glass substrate 2, and a rugged reflection plate 11 is provided on its bottom surface. Incident light from the display surface side of the upward substrate 1 is diffused when it passes through the isotropic diffusion layer 5, and passes through a common electrode layer 6, an oriented film 7 and the liquid crystal layer 3. Then, the incident light passes through the oriented film 9, an electrode layer 8, the substrate 2 and the 1/4λ plate 10 to arrive at the rugged reflection plate 11. Then, the light reflects according to the rugged shape of the rugged surface 12 of the rugged reflection plate 11. These reflected light emit from the display surface side of the upward substrate 1. |
