摘　　要：本工作研究了d/p窗口宽度的影响因素,发现减小液晶材料的（K_(33)/K_(11)）/（Δε/ε）值和（K_(33)/K_(22)）值,选择HTP值较大的手性添加剂,选择预倾角较大的定向材料可拓宽d/p窗口的宽度,因而为STN—LCD制作时选择原材料,制定d/p值提供了理论依据。d/p window or d/p margin is one of the most important parameters in STN-LCD manufacture. In our research, we found that liquid crystals with small (K33/K11)/(△ε/ε ) and, K33/K11 chiral dopants with large HTP values , orientation material with large prctilt angle must be chosen in order to widden d/p window, further to minimize the occurance the undertwist with no electric field and striped domains with electric field.
