Abstract: There is provided an optical laminate that can achieve a liquid crystal display apparatus in which the occurrence of moire is suppressed, and which is excellent in brightness and viewing angle characteristic. An optical laminate of the present invention includes in the stated order: a polarizer; a light-diffusing pressure-sensitive adhesive layer; a matte layer; and a louver layer. The louver layer has light-transmitting portions each having a trapezoidal section arrayed along a film plane, and light-absorbing portions each having a trapezoidal section arrayed between the light-transmitting portions. A haze value H of the light-diffusing pressure-sensitive adhesive layer and a bias angle B of the louver layer satisfy relationships represented by the following expressions (1) to (3): 2≤B≤6 (1) 20≤H≤60 (2) B×H≥40 (3) where the bias angle means a tilt angle of each of the trapezoidal sections with respect to a normal direction.

Abstract: An object of the present invention is to provide an optical laminate that can achieve a reflection-type liquid crystal display apparatus excellent in viewing angle characteristic. An optical laminate of the present invention includes a polarizer; a retardation layer configured to substantially function as a λ/4 plate; and a light-diffusing layer. When a transmitted light intensity in a direction corresponding to a polar angle of 10° and a transmitted light intensity in a direction corresponding to a polar angle of 60° when straight light is caused to enter the light-diffusing layer are defined as I10 and I60, respectively, a value for a ratio “I10/I60” is 30 or more. The optical laminate is used in a reflection-type liquid crystal display apparatus.
