摘要

液晶顯示器已經廣泛運用於家庭及一般公眾場合，該面板上下層由兩片偏光膜貼合而成，組成偏光板的TAC膜表面因硬度不夠易受刮傷，以及外界眩光反射造成螢幕對比度不佳，為了改善顯示器面板品質，因而衍生硬化處理、與抗反射處理技術需求。
本文針對防眩光薄膜技術進行探討，藉由增加面板的表面粗糙度使得外界光源均勻在螢幕表面散射，達成降低眩光的功能。本研究之薄膜以紫外光硬化樹脂製備；其配方組成含寡聚物、單體、光起始劑、溶劑及添加劑，本實驗使用的添加劑為無機氧化物及有機物粒子如：Clay、P.S之添加，觀察不同無機微粒子的添加量對表面粗糙度的改變以及增加表面光散射的影響，此外整體配方經特定光起始波長進行硬化後，比較光學穿透率與霧度在光學特性上的差異亦將一併討論之。

Liquid crystal display monitors have been widely used in the family and general public occasions. The top and bottom layers of panel are attached two pieces of polarizer. The TAC film surface which forms the polarizer is insufficiently hard and polarizer easily scratched. External glare reflection causes poor contrast for the screen. In order to improve the quality of monitor panel, hard coating treatment and reflection-resistant treatment have been derived. This article focuses on examining anti-glare film technique by increase of screen surface roughness , external light can be dispersed evenly over the screen surface; this has the function of lowering glare.
The film in this study is created with ultraviolet curable resin; the formula of production includes oligomer, monomer, photoinitiator, solvents and additives. The additives in this experiment are inorganic and organic oxides particles such as Clay, P.S to observe changes in surface roughness and increasing surface light scattering caused by adding different inorganic particulates. Additionally, after the overall formula has undergone curing at specific wavelengths, the differences in optical characteristics of transmittance and haze will also be discussed.
