Embodiment Construction

[0021] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0022] figure 1 It is a structural diagram showing the manufacturing process of the polarizer of the present invention, figure 2 is a configuration diagram showing the configuration of a preferred embodiment of the polarizer according to the present invention.

[0023] According to the above illustration, when the description is centered on the manufacturing process of the polarizer, there is a spacer 10 that functions as a mold for manufacturing the polarizer. In addition, molded bodies 12 serving as molds together with the spacers 10 are respectively provided on the upper and lower portions of the spacers 10 . Furthermore, an adhesive polyvinyl alcohol film 20 and a TAC film are located between the above-mentioned molded body 12 .

[0024] The production process of the above-mentioned polyvinyl alcohol film 20 is briefly described....

Abstract

The present invention provides a polarizing film capable of improving adhesive force between TAC film and CR-39 monomer, a polarizer and a manufacturing method thereof. In the invention, surface of the TAC film is treated by coating film to form a coating film. Furthermore, TAC film is bonded onto both sides of polyvinylalcohol film for protect the polyvinylalcohol film. CR-39 monomer is bonded on the surface of the TAC film with the coated film. In another aspect, the coating film treatment is carried out preferably in commissure die head manner. Thus effects of preventing drop of CR-39 monomer and improving durability are provided because the adhesiveness of the CR-39 with the TAC film is improved.

Description

technical field [0001] The present invention relates to a polarizer, and more particularly, to a polarizing film that provides adhesion to CR-39 adhered to the outermost layer of the polarizer, a polarizer, and a manufacturing method thereof. Background technique [0002] The so-called polarizing film refers to a film having the property of being able to distinguish the vertically polarized component or the horizontally polarized component of incident light and make it pass or block it. Although the intensity of the light emitted from the backlight of the liquid crystal display (LCD) module is equal in the entire direction, the function of the polarizer is to transmit only the light component in the same direction as the polarization axis in the light and absorb it. Or reflect other components of light to produce polarized light in a specific direction. [0003] The above-mentioned polarizing film is widely used in fields requiring polarized light such as image display devi...
