AG-BASED OPTICAL REFLECTIVE FILM AND A LIQUID CRYSTAL DISPLAY DEVICE COMPRISING THE SAME

摘要

An Ag-based optical reflective film and a liquid crystal display having the same are provided to prevent growth of crystal grain of Ag and coagulation of Ag atom and to obtain a high light reflection rate. An optical reflective film used as a reflective electrode or a reflective plate of a liquid crystal display device comprises Ag based alloy consisting 0.01 to 4 atom%, which is the total content of Bi and Sb contents, remaining Ag, and unavoidable impurities. The Ag based alloy contains 0.01 to 2 atom% of rare metallic atom. The rare metallic element is Nd or Y.
