摘要：近年来液晶显示器件朝着彩色化和大型化方向发展，户外应用也将越来越多，紫外光对液晶器件产生影响也逐渐显现出来，防紫外光将越显重要。通过测量ITO玻璃及偏光片对各波段紫外光的光谱特性，分析比较一般偏光片(LN-1205T)和防紫外偏光片(F-1225DU)的紫外透射光谱，偏光片F-1225DU对紫外线有比较好的吸收，能挡住各种波长的紫外光。使用防紫外F-1225DU偏光片的新型液晶显示器，能较好的解除紫外的影响，从而提高了户外型液晶显示器产品的性能。

Abstract：As liquid-crystal display is developing to be used outside and becomes colorful and larger, the influence of ultraviolet on liquid-crystal display is becoming more and more apparent． And the anti-ultraviolet character of liquid-crystal display becomes more important． In this paper, the spectroscopic characteristics of ITO glass and polaroid were measured with ultraviolet of various wavelengths. By comparing the ultraviolet transmission spectrum of normal polaroid (LN-1205T) with that of anti-ultraviolet polaroid (F-1225DU), the anti-ultraviolet characteristic of a new style liquid-crystal display (LCD) was discussed. And the results show，the anti-ultraviolet polaroid (F-1225DU) is better in the absorption of ultraviolet． The anti-ultraviolet polaroid (F-1225DU) can enhance the performance of liquid-crystal display used outside．
