FIG. 1 shows the structure of a liquid crystal element using the alignment control film of the present invention. A transparent electrode 12 made of indium/tin oxide is placed on a substrate 11 made of glass, plastic, etc.
After forming an orientation control film 13 thereon, an orientation treatment is performed, and a sealing resin 14 including a spherical spacer is printed.
Two liquid crystal support plates 15 were pasted together, liquid crystal 16 was injected through the opening of the spacer 14, and the opening was sealed to complete a so-called liquid crystal element. Figures 3(a) and 3(b) show the electro-optical properties of a ferroelectric liquid crystal cell prepared by the above method using a protein coating film containing an electron-accepting quinone compound as an alignment control film. . O in the figure is the maximum relative brightness when voltage is applied, indicating the bulk response,
× is the relative brightness after scanning a series of measurement waveforms for 1000 lines, and represents a memory response. This figure shows a steep threshold and good bistability. Furthermore, this bistability was maintained over a long period of time. On the other hand, in a ferroelectric liquid crystal device using a proteinaceous coating film that does not contain an electron-accepting quinone compound, as shown in FIGS. 4(a) and 40(
As shown in g)), its bistability deteriorated within 24 hours.
