LIGHT REFLECTING PLATE, LIGHT REFLECTING PLATE FOR REFLECTION TYPE LIQUID CRYSTAL DISPLAY DEVICE, AND LIGHT-REFLECTING ELECTRODE PLATE FOR REFLECTION TYPE LIQUID CRYSTAL DISPLAY DEVICE

摘要

PURPOSE: To provide a light reflecting plate which uses silver having excellent reflection characteristics of light and does not deteriorate with time, to provide a light- reflecting plate for a reflection type liquid crystal display device, and to provide a light-reflecting electrode plate for a liquid crystal display device. ;CONSTITUTION: This light-reflecting electrode plate 1 consists of a glass substrate 11, adhesive layer 12 formed into an electrode shape accurately positioned, silver light-reflecting metal electrode 13, transparent inorg. thin film 14, and moisture-resistant transparent thin film 15 which covers these three layers 12-14 to protect the surface and side faces of the layers. The adhesive layer and the transparent inorg. thin film consist of indium oxide thin films with addition of 3atom% zirconium oxide. The moisture-resistant transparent thin film 15 consists of silicon oxide. The transparent inorg. thin film 14 is firmly adhered to both of the light-reflecting metal thin film 13 and the moisture-resistant transparent thin film 15 to integrate these three layers. Further, the moisture-resistant transparent thin film 15 firmly adhered to the layers protects the light-reflecting metal thin film 13 from sulfur compds. or water content in air and improves the storage stability of the plate.;COPYRIGHT: (C)1996,JPO
