A vacuum insulation material includes a pair of gas barrier exterior materials, a core material including a cellulose structure having porosity of greater than or equal to about 80% under reduced pressure of about 1 Pa, where the cellulose structure has a unit length of greater than or equal to about 1 &#x3bc;m and less than or equal to about 5 mm in the heat-insulation direction, and the method of manufacturing the same, and a gas adsorption agent, where the core material and the gas adsorption agent are interposed between the pair of gas barrier exterior materials and sealed inside of the pair of gas barrier exterior materials under reduced pressure.

Vacuum insulation material

A vacuum insulation includes a core material and a gas adsorption agent interposed between a first gas barrier material and a second gas barrier material, wherein the first and the second gas barrier materials sealingly enclose the core material and the gas adsorption agent, and wherein at least one of the first and the second gas barrier materials includes a laminate including a copper alloy foil and a polymeric material.

The present invention provides a light guide plate for emitting light radiated from a light source disposed at a side of the light guide plate. The light guide layer has a light incidence side for internally introducing light emitted from the light source at the side thereof; a polarization separation layer comprising a first matrix layer and a first fiber having birefringence and disposed more toward the light emission side than the light guide layer; a low refractive index layer having a lower refractive index than the refractive index of the first matrix layer; and an angle improvement layer comprising a second matrix layer having a second fiber disposed inside the second matrix layer.

Light guide plate, planar light apparatus, and display device

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.
