Provided is a method for preparing a silica layer, comprising bringing to gelation a precursor layer formed from a precursor composition comprising a silica precursor, an acid catalyst and a surfactant.

Preparation method of silica layer

The present application relates to a method for producing a silica film, which includes a step of contacting a silica precursor layer formed of a silica precursor composition having a pH of 5 or less with a Lewis base, where the silica precursor composition includes a silica precursor formed from a silane compound and an acid catalyst. The present application can provide a method capable of forming a silica film having excellent resistance to a vertical load and a tangential load without going through expensive equipment or a high temperature process.

Production method of silica film

The present invention relates to a polarizing plate including: a polarizer and a protective layer formed on at least one surface of the polarizer, in which the protective layer is a cured product of a radical curable composition including: (A) a first compound represented by [Formula 1]; (B) a second compound represented by Formula B; and (C) a radical initiator, and an image display device including the same.

Polarizing plate and image display apparatus comprising same

The present specification relates to a (meth)acrylate compound, and a copolymer and a homopolymer including a repeating unit derived therefrom.

(Meth)acrylate compound, and copolymer and homopolymer comprising repeating unit derived from same

The present invention relates to a polarizing plate including a polarizer, and a protective layer formed on at least one surface of the polarizer, in which the protective layer is a cured product of (A) a first compound represented by the following [Formula 1]; (B) a radical curable second compound including at least one carboxyl group conjugated to an unsaturated double bond between carbons present at a side chain in a molecule thereof; and (C) a radical curable composition including a radical initiator, and a liquid crystal display device including the same.

Polarizing plate and image display device comprising same

The present invention relates to a radical-curable adhesive composition including a first compound represented by [Chemical Formula I]; a radical-curable second compound including at least one carboxyl group conjugated with a carbon-carbon unsaturated double bond present in the side chain in the molecule; and a radical initiator, and a polarizing plate including the radical-curable adhesive composition.

Radical curable adhesive composition and polarizing plate comprising same

The present specification relates to a polarizing plate and a display device comprising the same.

There is provided a condensing film for an LCD backlight unit. The condensing film includes a base member unit; a condenser unit disposed in an upper surface of the base member unit and having unit lens groups sequentially arranged thereon, each of the unit lens group being composed of a combination of at least two lenses that are different in shape; and a reflector unit disposed in a lower surface of the base member unit and composed of an opening through which light passes and a reflective surface from which the light reflects. The condensing film configured thus may be useful to solve the problems regarding the viewing angle and the uniformity in brightness of a screen since the condensing film has a more moderate distribution of emitted light than the conventional condensing films.
