摘要： A light diffusion film (20) having small back scattering can be obtained by using fibers having two kinds of birefringent regions (21A) and (21B). An outer portion of fiber (21) is a first birefringent region 21A and an inner portion of fiber (21) is a second birefringent region (21B). While the first birefringent region (21A) is in contact with a transparent resin (22), the second birefringent region (21B) is not in contact with the transparent resin (22). When a refractive index (n1) in major axis direction of the first birefringent region (21A) is a value between a refractive index n2 in major axis direction of the second birefringent region (21B) and a refractive index n0 of the transparent resin (22), interface reflection between the transparent resin (22) and the fiber (21) can be reduced, which leads to obtain a light diffusion film (20) having small back scattering.

摘要： A light diffusing film having superior productivity can be obtained by using very short fibers as a substitute for conventional spherical fine particles as light diffusing material. It is possible to mass-produce very short fibers at low cost, for example, by cutting fibers. Further, it is relatively easy to obtain very short fibers with a narrow fiber length distribution. The use of this makes it possible to carry out more highly sophisticated optical design of light diffusing films.

摘要： A polarizing plate with optical compensation layers that performs a wide viewing angle compensation with respect to a liquid crystal cell, allows circularly polarized light to be obtained over a wide range of light wavelengths, contributes to the reduction in thickness, prevents thermal irregularity from occurring, and can effectively prevent light leakage from occurring in a black display. The polarizing plate includes a polarizer, a first optical compensation layer, and a second optical compensation layer that are stacked together in this order. The first optical compensation layer is formed of a liquid crystal compound and has a relationship of nx>ny=nz and an in-plane retardation Re1 of 100 to 170 nm. The second optical compensation layer has a relationship of nx=ny>nz and a thickness direction retardation Rth2 of 30 to 400 nm. The angle formed between the absorption axis of the polarizer and the slow axis of the first optical compensation layer is in the range of “plus” or “minus” 25 to 65 degrees.
