PURPOSE:To provide plural linear high resistance layers in a belt shape on one or more of transparent conductive films and to obtain a display with a uniform gradation by the constitution wherein a transparent conductive film, light absorptive film, light reflective film, liquid crystal orientation film, liquid crystal layer, liquid crystal orientation film, transparent conductive film and transparent substrate are successively laminated on a transparent substrate. CONSTITUTION:Transparent conductive films 21, 26 are formed respectively on transparent substrates 20, 27, and one or both films 21, 26 are trimmed by an etching method or a laser beam to form high resistance regions 30 having several 10mu width. A light absorptive film 22 is formed of a compd. semiconductor, etc. of MgSi, etc. on the one film 21 and a reflection film 23 is formed on the film 22 by vapor deposition of Al. Orientation films 24 are provided respectively on the film 23 and the film 26 by vapor deposition of SiO2, etc. A smetic liquid crystal 25 is sealed between both substrates 20 and 27, whereby a liquid crystal light bulb is obtd. Electric current is conducted to the film 21 in a system of writing an image with laser light 1 by the regions 30 and reading the image with the reflected light of incident light 11, and when the smetic liquid crystal phase is changed to the liquid phase, the liquid phase is uniformly heated and changes to the uniform liquid phase. The display having uniform contrast is thus obtd. |
