摘　　要：该文研究了电场作用下扭曲向列相液晶盒颜色变化的规律。研究发现,当起偏器与检偏器两偏光片呈35°时,液晶盒在无电场的情况下,偏光干涉色基色呈浅红色;当电压达到1.8 V以上时,液晶盒依次呈现绿、蓝、红等颜色,当电压达到饱和电压3.1 V时,又呈现无色。该文利用偏光干涉原理对产生该现象的原因进行了分析。In this paper, the law that the color of the twisted nematic liquid crystal cell changes with the voltage is studied. It is found that when the polarizer and analyzer is at a 35 degree angle and the liquid crystal cell is in the case of no electric field, the po- larized light interference color presents the light red. After the voltage reaches 1.8V the liquid crystal presents green, blue and red et al in turn, and when the voltage reaches saturation voltage 3.1V the liquid crystal cell would present no color. The reason of the phe- nomenon is analyzed by using the principle of polarization interference.
