PURPOSE:To provide the liquid crystal display body consisting of a high-polymer/liquid crystal composite film (hereafter abbreviated as PDLC) which is bright and does not require a back light by forming many layers of metallic thin-film layers on reflection electrodes and using these layers as interference layers to prevent the electrodes from acting like mirrors. CONSTITUTION:This element has a reflection film 8 on one side of the PDLC 1 and is further laminated with many layers of the metallic thin-film layers 10 on this reflection plate 8 in such a manner that these films are commonly used as the electrodes. The interference effect by the metallic thin-film layers cannot be expected while voltages are not impressed to the PDLC 1 and, therefore, the display element is white. The PDLC 1 becomes transparent when the voltage is impressed to the PDLC 1 to put the PDLC into a light transparent state. Visible light, therefore, arrives at the metallic thin-film layers 10 and the interference meeting the number of layers and film thicknesses of the formed metallic thin-film layers 10 and the refractive indices of the constituting metals thereof takes place and these layers are colored. The layers turn black to dark purple if optimum conditions are selected. Namely, the black to dark purple display is possible if the voltage is impressed. |
