摘要

针对于液晶显示器出现的侧视角发红不良，本文从定性及定量角度进行机理分析。初步实验定性确定影响侧视角发红的主要因素为材料

和颜料颗粒分布。定量分析方面，通过对

、膜层厚度、上偏振片偏振方向与主观察方向的夹角（A-UPMO）、透过光主波长4个方面的分析，得到侧视角不良程度的理论计算公式。根据上述结论，通过减小

，减薄膜层厚度以及缩小A-UPMO可以有效改善不良程度。给出通常情况下，新材料开发过程中Red/Green/Blue

的阈值分别为6.0 nm/5.4 nm/4.0 nm，为未来新材料开发及不良改善提供有益的参考。

Abstract

The mechanism of side-view reddish in LCD is analyzed by the qualitative and quantitative side in this paper. The qualitative result shows that the main factors which influence the side-view reddish are

and pigment particle distribution of the material. In the quantitative analysis

the theoretical formula which can simulate the level of side-view reddish is obtained by analyzing

thickness of the film

angle between upper polarizer's polarization direction and main observation direction (A-UPMO) and the main wavelength of the transmitted light. According to the above conclusions

side-view reddish can be improved effectively by reducing

thinning film thickness and reducing the A-UPMO. In general

the threshold of

for Red/Green/Blue material each is 6.0 nm/5.4 nm/4.0 nm. The research will give guiding theory for new material development and issue improvement in the future.
