Abstract: The invention has modified the conventional LCD structure, wherein a polarizing film is directly coated in the liquid crystal cell instead of the conventional polarizing plate, which is glued on the outer side of the liquid crystal cell. Then, the invention can prevent the direct contact between the polarizing film and the touch panel of film film (FF) type or in film plastic (FP) type. Thus, the touch panel on the LCD panel can adapt various technologies, so that the touch panel of FF type can be used without worrying about the damage on the polarizing film due to the pressure while a point touch is applied on the touch panel. Also and, for the touch panel of FP type, a conductive film can be directly coated on the panel substrate. The invention uses the coating polarizing film as an extraordinary mode (e-mode) polarizer. Also and, an ordinary mode (o-mode) polarizer can also be adapted, so as to expand the large viewing angle in good polarizing effect.

Abstract: This invention discloses a photosensitive phosphorylated phenol-formaldehyde resin, characterized by containing in its molecule at least two phosphate groups, each phosphate group coupled with at least one photo-sensitive group. The photosensitive resin of the present invention is prepared by reacting a phenol-formaldehyde resin with phosphorus oxychloride to form a phosphorylated phenol-formaldehyde resin; then reacting the resin with a compound having one hydroxyl group and at least one ethylenically unsaturated bond, thereby esterifying some of the phosphorochloridate groups to produce a resin having ethylenically unsaturated bonds and unreacted phosphorochloridate groups; and hydrolyzing the unreacted phosphorochloridate groups into phosphoric groups. The photosensitive resin according to the invention is UV-curable and alkaline-soluble as traditional photosensitive resins are; moreover, it exhibits good flame retardant and adhesive properties.
