<P>PROBLEM TO BE SOLVED: To provide an antiglare polarization film laminate having low haze, high antiglare function and improved view angle characteristic, and to apply the antiglare polarization film laminate to a TN-type liquid crystal display. <P>SOLUTION: The antiglare polarization film laminate 10 is composed by laminating an antiglare layer 11 having fine ruggedness, a linear polarizer 30 and an optical anisotropy layer 40 in the described order and arranging the laminate on the viewing side of a liquid crystal cell 50. The haze ratio of the antiglare layer 11 is 5% or smaller, the total of reflective visibility measured at an incident angle of 45° using three kinds of optical combs in which the width between the dark part and the bright part is 0.5 mm, 1.0 mm and 2.0 mm, respectively, is 50% or smaller, and then, to the incident light at an incident angle of 30°, the reflectivity R(30) of specular reflection is 2% or smaller, the reflectivity R(40) at a reflection angle of 40° is 0.003% or smaller, and also, with the reflectivity in a direction at an reflection angle of 60° or larger, the value of R(≥60)/R(30) is 0.001 or smaller. The average area of a polygonal shape when Voronoi division is performed by taking the vertex of the projected part of the surface as a generatrix is 50 to 1,500 μm<SP>2</SP>. The optical anisotropy layer 40 is optically negative or positive uniaxial and the optical axis is tilted by 5 to 50° with respect to the normal of the film. <P>COPYRIGHT: (C)2008,JPO&INPIT |
