PURPOSE:To offer a high polymer, liquid crystal composite film (PDLC) liquid crystal display body which eliminates the need for a bright back light by forming a multi-layered metallic thin film layer as an interference layer on an element electrode and coloring the interference layer by utilizing an interference color. CONSTITUTION:The element electrode 8 is formed on one side of the PDLC 1 and a multi-layered metallic thin film is laminated on the top or reverse surface of the element electrode 8; and incident light is scattered unless a voltage is applied to the PDLC 1, so a display element is in white. When the PDLC 1 is applied with the voltage and put in a light transmission state, the PDLC 1 becomes transparent, so the visible light reaches the metallic thin film layer 10. Then, interference corresponding to the number of layers, the film thickness, and the constituent metal of the formed metallic thin film layer 10 is caused and the interference color is generated to color the layer. The black - dark purple colors are obtained by selecting optimum conditions. Namely, a black - dark purple display is made by applying the voltage. |
