Abstract

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.
