Embodiment Construction

[0036] Figure 2A Shows a schematic diagram of a preferred embodiment of the present invention, and Figure 2B Illustrate Figure 2A Flow chart of the manufacturing method. First, a first protective layer 206 is provided. The material of the first protective layer 206 is selected from the group consisting of cyclic olefin copolymer (coc) and cyclic olefin polymer (cop) ( Step 222).

[0037]Cyclic olefin copolymers and cyclic olefin polymers have good moisture resistance. Moreover, since the cycloolefin copolymer and the cycloolefin polymer have high transparency and small tortuosity, they also have excellent optical properties, such as average wavelength dispersion and good optical isotropy. In addition, cycloolefin copolymers and cycloolefin polymers have low moisture absorption, low moisture permeability, and high heat resistance. In other words, the protective layer 206 can maintain a stable size even in a high-temperature and high-humidity environment.

[0038] Then, the linea...

Abstract

A polarized light plate consists of the first protection layer, linear polarized light layer and the second protection layer. Its preparing method includes providing the first protection layer prepared by material of group formed from cycloolefine multipolymer and cycloolefine polymer, sticking a linear polarized light layer on the first protection layer by the first adhesive layer and sticking the second protection layer made by the same material as the first one on linear polarized light layer by the second adhesive layer.

Description

Technical field [0001] The present invention relates to a polarizing plate and a manufacturing method thereof, and in particular to a polarizing plate that can be used in a flat panel display and a manufacturing method thereof. Background technique [0002] Liquid crystal displays have the advantages of high image quality, small size, light weight, low voltage drive, low power consumption and wide application range. Therefore, it is widely used in consumer electronics or computer products such as medium and small portable TVs, mobile phones, camcorders, notebook computers, desktop monitors, and projection TVs, and has gradually replaced cathode ray tubes (cathode ray tubes). tube, CRT) has become the mainstream of displays. [0003] In the liquid crystal display, the polarizing plate is one of the main components of the liquid crystal panel. Figure 1A A schematic diagram of a known polarizer is shown. Such as Figure 1A As shown, the polarizing plate 100a includes a first protec...
