Abstract:
A reflecting type liquid crystal display device comprising:two substrates, a liquid crystal layer inserted between the substrates, a reflecting surface which reflects light passing through this liquid crystal layer, and a light diffusion layer which at least diffuses the light reflected by the said reflecting surface, wherein said light diffusion layer is formed of 2 types of refractive index medium with differing refractive indices, and when the refractive index of the first refractive index medium is nA(400) at light wave length 400 nm, and nA(700) at light wave length 700 nm, and the refractive index of the second refractive index medium is nB(400) at light wave length 400 nm, and nB(700) at light wave length 700 nm, then, (nA(400/nA(700))Ã—0.9 &lE;(nB(400)/nB(700))&lE;(nA(400)/nA(700))Ã—1.1.
