    摘要: 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.

    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.
