Transmission light-scattering layer sheet and liquid crystal display |
摘要 |
The reflective liquid crystal display device comprises a polarizing plate disposed forwardly of a liquid crystal cell, a relector which is disposed on backside of the liquid crystal cell and reflects an incident light, and a light-scattering sheet which is disposed forwardly of the reflector and scatters the incident light isotopically. The light-scattering sheet can be prepared with the use of a spinodal decomposition method of coating a mixture liquid containing a plurality of polymers varying in refractive index on a transparent support and evaporating or removing a solvent to form a light-scattering layer having a droplet phase structure. The light-scattering layer includes a light-scattering layer showing a maximum intensity of the scattered-light at scattering angles of 3 to 40°, and a light-scattering layer showing maximums intensity of the scattered-light respectively at smaller angles of 2 to 2° and larger angle thetab.
