Information recording medium

Abstract

Abstract PURPOSE:To widen the driving voltage width between respective bright and dark states and to improve a gradation characteristic by laminating many films varying in fine pore diameter as high-polymer/liquid crystal dispersed films. CONSTITUTION:A photoconductive film 12 for information recording and the high-polymer/liquid crystal dispersed films 3 for information reading out are laminated and formed. The high-polymer/liquid crystal dispersed films 30 are formed by laminating at least two layers 32, 34 varying in the sizes of the fine pores in the high-polymer films dispersed and held with liquid crystals. The size of the fine pores in the high polymer including the liquid crystals varies with the kind, film thickness, etc., of the high polymer. The driving voltage value of the bright state and the dark state vary if the size of the fine pores changes. The change in the light transmittance by a driving voltage change is, therefore, the superposition of the characteristics of the respective layers 32, 34 if the many films varying in the size of the fine holes are laminated. The driving voltage width of the brightness and darkness is widened and the gradation characteristic is improved in this way.
