Abstract

A method for manufacturing a polarizer sheet includes: preparing a light transmission film where a metal thin film is formed, and forming metal patterns by irradiating a polarized pulse laser beam onto a plurality of regions of the metal thin film.

Description

technical field [0001] The present invention relates to methods of making polarizer sheets. Background technique [0002] Recently, various flat panel displays have been developed in order to replace bulky and bulky cathode ray tubes (CRTs). [0003] Examples of flat panel displays are liquid crystal displays (LCDs), field emission displays (FEDs), plasma panels (PDPs), electroluminescence displays (ELDs), and the like. Various attempts have been made to provide improved display quality and large screens for flat panel displays. [0004] Among flat panel displays, an LCD is a non-luminous display device that displays images using a light source such as a lamp. [0005] LCDs have the advantages of small size, light weight, and low power consumption. LCDs display images using electrical and optical properties of liquid crystals injected within a liquid crystal panel. [0006] Unlike a CRT, the liquid crystal injected between the TFT substrate and the color filter substrate...
