LIQUID CRYSTAL POLYMER FILM, LAMINATED SHEET FOR OPTICAL ELEMENT WHICH USES THE FILM, AND OPTICAL ELEMENT COMPRISING THE SHEET

摘要

To provide a film for optical element made of liquid crystal polymer whose productivity and economical efficiency are improved; a laminated sheet formed by bonding this film to a polarizing plate; and an optical element which can be optically inspected, and used under an environment of high temperature and high moisture, and whose surface hardness is so high that the surface is not easily damaged. A long laminated sheet for optical element comprising a liquid crystal polymer layer, and a polarizing film layer; and a long laminated sheet for optical element comprising at least a liquid crystal polymer film layer oriented in the direction oblique to the MD direction at a given angle, and a polarizing film layer. An optical element having a laminated structure formed by laminating a layer of a cured acrylic resin having optical isotropy, an orientated liquid crystal polymer layer, a layer of pressure-sensitive adhesive, and a translucent base layer in that order; and a long laminated sheet for optical element having a laminated structure formed by laminating a layer of a cured acrylic resin having optical isotropy; an orientated liquid crystal polymer layer; a layer of pressure-sensitive adhesive; and a translucent base layer in that order, and containing liquid crystal polymers orientated in the MD direction at an arbitrary angle.
