Abstract:
A reflection-type liquid crystal display device comprising:a liquid crystal cell; a polarizing film; a birefringent film; a scattering layer; and a light reflection means, wherein said scattering layer has a diffuse reflection factor â€œRâ€  of 7% or greater but 110% or less when an incident angle of light is within a range of 25Â° and 45Â°, provided that said diffuse reflection factor â€œRâ€  is defined according to the formula â€œRâ€ =R1/R2Ã—100 â€ƒwhere R1 is a reflection factor in a direction of the normal line of an object when light is irradiated at an incident angle of 0Â° to said object adhered onto an aluminum mirror reflection plate having a reflection factor of 91% in a direction of the normal line thereof to incident light of 546 nm in wave length at an incident angle of 0Â°, and R2 is a reflection factor in a direction of the normal line of an MgO layer when light is irradiated to said MgO layer at an incident angle of 25Â°, said MgO layer having a thickness equal to that of said object and adhered to said aluminum mirror reflection plate.
