摘要：

Polymer dispersed liquid crystalline (PDLC) films containing dichroic dye were prepared by the polymerization of HEMA, BMA and E 7 incorporated with dichroic dye under UV irradiation. Their eletro optical properties were measured. The results show that comparison with PDLC without the dye, its contrast ratio was enhanced, although T on decreased; the sharpness and τ on were not improved, τ off was slightly improved. These phenomena were discussed.
