| Abstract: | A polymer dispersed liquid crystal (PDLC) film that has good electro-optical properties is produced by the method of polymerized-induced
phase separation. Based on the application foreground, its capability parameters, such as contrast ratio, work voltage, and
visual angle, are characterized for the first time by a white light but not a fixed wavelength light. The results show the
PDLC film has a low work-voltage of 20 V, more than 150° visual angle, high stability, and long lifetime. The differences
between plastic and glass ITO-coated substrates of PDLC films are also studied in this paper. The plastic substrate has better
property and will have a wider perspective especially in the portable, tender and folded display devices. Due to adjustable
properties of film by electric field, PDLC has the potential application for display device, sensor, switch, grating, and
new generation analytical apparatus.
