Provided is a silica film, etc. not having the film strength thereof being easily degraded, even when hollow silica particles are contained therein. Further, provided is a silica film, etc. having a lower reflectivity. A silica layer (the silica film) comprises silica and fluorinated hollow silica particles. The silica is formed by converting polysilazane into silica. The fluorinated hollow silica particles are locally distributed on the surface of the silica layer. The part where the fluorinated hollow silica particles are localized has the function of a low refractive index layer, and the parts other than the part where the fluorinated hollow silica particles are localized have the function of a hard coat layer.

Silica film, optical member, and polarizing member

Provided is a polymer film in which metal oxide particles are localized to a great degree, wherein the polymer film is a hard coat layer that includes a binder including a first polymer component and a second polymer component that are miscible with each other and metal oxide particles that are unevenly distributed with a greater concentration toward at least one of a surface portion and the other surface portion opposite the surface portion, wherein the first polymer component may be hydrophilic, the second polymer component may be hydrophobic relative to the first polymer component, a proportion of the first polymer component may gradually decrease from the surface portion to the other surface portion, and the surface portion may be toward a substrate for forming the polymer film. An optical member, such as a polarization member, and a display device employing the polymer film are also provided.

Optical member, polarization member, and display device employing polymer film

Provided is a resin film, etc. not having the film strength thereof being easily degraded, even when an additive is used. Further, provided is a resin film, etc. having a lower reflectivity. A low refractive index layer (the resin film) comprises a binder. Further, the low refractive index layer comprises hollow particles distributed in the binder. Further, the low refractive index layer comprises a fluorine-containing polymer which is immiscible with the hollow particles. The fluorine-containing polymer which is immiscible with the hollow particles is mostly distributed on the surface of the low refractive index layer.

Optical member having low refractive index layer

A light guide panel includes: a light guide layer having a light incident surface; a polarization separation layer configured to select a desired polarization among light emitted from the light guide layer and to emit light having the polarization; and a light homogenization layer including a plurality of fibers and a supporting medium of the fibers, the light homogenization layer configured to diffuse and scatter light incident on the light guide layer into the light guide layer. The polarization separation layer includes: a plurality of first fibers having birefringence; and a first supporting medium that is isotropic and configured to support the first fibers. The refractive index of the first supporting medium corresponds to at least one of two different refractive indices of the first fibers. The light homogenization layer includes: a plurality of second fibers having birefringence; and a second supporting medium that is isotropic and configured to support the second fibers.
