An object of the present invention is to provide a polarizer which is thin and light as well as has durability, and an optical member capable of forming a liquid-crystalline displaying apparatus for mobiles which is excellent in reliance. According to the present invention, there is provided a polarizer, which comprises a protecting film comprising an epoxy resin as a main component on at least one side of a polarizing film. This polarizer can be produced by a method of coating an uncured epoxy resin composition on at least one side of a polarizing film, and then curing the composition to form a protecting film. Also, an optical member comprising a laminate of the aforementioned polarizer and other optical layer exhibiting the optical function is provided and, further, a liquid crystal displaying apparatus comprising the optical member disposed on one side or both sides of a liquid-crystalline cell is provided.

Polarizer, process for preparing the same, optical member and liquid crystal displaying apparatus

A conventional liquid crystal display comprises a number of components, so that a manufacturing cost cannot be reduced. Furthermore, a large-area substrate has problems in shipping. According to this invention, a liquid-crystal panel is prepared by forming individual optically functional films, a TFT device and a light-emitting device on a long thin film and then laminating the film by a transfer process. A base film to be a substrate in a liquid-crystal panel preferably has a thickness of 10 &#x3bc;m to 200 &#x3bc;m, a curvature radius of 40 mm or less as a measure of flexibility and a coefficient of thermal expansion of 50 ppm/&#xb0; C. or less. Furthermore, it more preferably gives a variation of &#xb1;5% or less in mechanical and optical properties to a thermal history at 200&#xb0; C.

Light-condensing film, liquid-crystal panel and backlight as well as manufacturing process for light-condensing film

The object of the present invention is to provide a laminate polarizing plate of which application to liquid crystal displays is able to simplify constitutions and production procedures of the displays, and to reduce cost thereof; and to provide an industrially advantageous method of producing the compound polarizing plate, and a liquid crystal display using the same. The object is achieved by a laminate polarizing plate comprising a polarizing film, an adhesive layer and a phase retarder film which being laminated in this order, wherein said phase retarder film comprises at least one coating layer having refractive index anisotropy of which an in-plane retardation value (R) is 0 to 10 nm and a retardation value in the thickness direction (R') is 40 to 300 nm, wherein said coating layer is formed on a transfer substrate, followed by being transferred on a surface of the adhesive layer of the polarizing film.

Laminate polarizing plate, a method of producing the same and a liquid crystal display

An epoxy resin composition comprising (A) a bifunctional crystalline epoxy compound, (B) an amorphous trisphenolmethane type epoxy compound having three or more of epoxy groups in a molecule, and (C) an epoxy curing agent having phenolic hydroxyl groups. The resin composition has an excellent moldability (low viscosity and can be filled with filler with high density) and high softening point, and is used preferably as an encapsulating material for electronic device.

Epoxy resin composition and resin-encapsulated semiconductor device

A powder coating composition comprising as essential components: (A) polyester resin having at least two hydroxyl groups in a molecule, and (B) polyvalent organic cyanate having at least two cyanate groups in a molecule of the following formula and/or its prepolymer; ##STR1## wherein A is C1-C6 hydrocarbon group, and A may be different from each other;
