Abstract

A polarizer of a liquid crystal display device and a method for manufacturing a liquid crystal display device using the same is disclosed. The polarizer includes a main body, a protection film on the main body, and a cutting line formed on the protection film. A method for manufacturing a liquid crystal display device includes providing a liquid crystal panel and a protection film having an active region and a dummy region, the protection film including at least a cutting line in the dummy region or a boundary area between the active region and the dummy region; attaching the protection film to a polarizer; attaching the polarizer to a liquid crystal panel; and, removing the dummy region of the protection film along the cutting line from the liquid crystal panel.

Claims (7)

1. A method for manufacturing a liquid crystal display device, the method comprising:

providing a liquid crystal panel and a polarizer having a main body for polarizing incident light and a protection film having an active region and a dummy region surrounding the active region, the protection film including a cutting line along the boundary between the active region and the dummy region, the protection film being disposed directly on the main body;

attaching the protection film to a polarizer;

removing the dummy region of the protection film from the polarizer, exposing a dummy area of the polarizer;

assembling the liquid crystal display panel and a top case to cover the dummy area of the polarizer and form the liquid crystal display module;

supplying the assembled liquid crystal display module to a user; and

removing directly the action region of the protection film by the user.
