The liquid crystal display grows vigorously further in recent years, from inch-size portable devices to the large (LCD TV) of hundred inches. Thinner, lighter, and low power consumption are still the driver s for technology development.Among them the making of each procedure all widely uses the macromolecule, it is an major trend for developing the key material of high performance. The major concern of this thesis is on the optical efficiency improvement for films applied in back-light module, adopt organic/inorganic hybrid technology, make up the adjustment of formulations, probe into the photoelectric function film which develops high additional value, affords film with abrasion resistance,adhesion, high hardness, high brightness enhancement,chemical resistance,excellent weathering resistance characteristics ,etc..
