摘要:
A multilayer reflective polarizer substantially rotationally symmetric about an optical axis passing thorough an apex of the multilayer reflective polarizer and convex along orthogonal first and second axes orthogonal to the optical axis is described. The multilayer reflective polarizer has at least one first location having a radial distance r1 from the optical axis and a displacement s1 from a plane perpendicular to the optical axis at the apex, where s1/r1 is at least 0.1. The multilayer reflective polarizer may have at least one inner layer substantially optically uniaxial at at least one first location away from the apex. For an area of the reflective polarizer defined by s1 and r1, a maximum variation of a transmission axis of the reflective polarizer may be less than about 2 degrees.

A display device includes a display panel which displays an image with light, a backlight unit which generates and provides the light to the display panel, and a polarizer which is coupled to the display panel and includes a polarizing film to polarize the light. The polarizing film includes a base film defining a first optical surface thereof from which first grooves are defined recessed and a second optical surface thereof which opposes the first optical surface and from which second grooves are defined recessed; a polarizing layer including the first grooves recessed from the first optical surface; and a light blocking layer including the second grooves recessed from the second optical surface.

A transparent resin layer (A) having a surface resistance of 1.0×1013Ω/□ or less is placed more on the viewer side than the most viewer side polarizing film (1) in an image display device (B). The transparent resin layer (A) can be made from a transparent pressure-sensitive adhesive or a transparent liquid resin. Without degrading the reliability of the most viewer side polarizing film (1), the transparent resin layer (A) can impart an antistatic function at such a level as not to reduce the sensitivity of a touch panel.

摘要:
Multilayer reflecting polarizing films are disclosed having increased in-plane refractive index differences between adjacent microlayers along both the pass and block axis, and having negative refractive index differences between adjacent microlayers along the thickness or z-axis. Major front and back surfaces of the film exposed to air provide a Fresnel reflectivity component to the pass axis reflectivity, and the microlayers provide a microlayer component to the pass axis reflectivity, such microlayer component preferably having a reflectivity of p-polarized light that increases with incidence angle faster than the Fresnel reflectivity component decreases so as to substantially avoid off-axis gain peaks for p-polarized light. The films preferably utilize a relatively small total number of microlayers, arranged in a single coherent stack with monotonic optical repeat unit thickness profile, and at least some microlayers preferably include polyethylene naphthalate or a copolymer thereof.
