POLARIZING PLATE AND IMAGE DISPLAY DEVICE COMPRISING THE SAME
A polarizing plater includes a polarizer, a protective film disposed on at least one surface of the polarizer, and a diffusing adhesive layer and a transparent adhesive layer interposed between the polarizer and the protective film. The diffusing adhesive layer includes a diffusing particle. The diffusing particle includes a first diffusing particle and a second diffusing particle which have different average diameters from each other.

Polarizer, Display Device Having the Polarizer, and Method of Fabricating the Polarizer
Penetration of moisture and propagation of cracks is prevented in a polarizer. An adhesive is provided to cover one or more edges of the polarizer to seal the side section of the polarizer. The adhesive fills initial cracks to prevent the initial crack from being propagated to the inside of the polarizer. A protective film and the adhesive include a material having a hydrophobic characteristic. In a method of fabricating a polarizer, a polarizing film is shaped to form a polarizing layer, and a protective film is then attached by applying an adhesive onto the edges of the polarizing layer. Then, the adhesive is cured, and the protective film having the polarizing layer attached is processed, thereby dividing the protective film into a plurality of polarizers. The adhesive can firmly fix the crack since the adhesive is fills in cracks in the polarizing layer.
