Heat-resistant reflecting layer, laminate formed of the reflecting layer, and liquid crystal display device having the reflecting layer or the laminate

摘要

A heat-resistant reflecting layer includes Ag as a main component, a 0.1-3.0 wt% first element selected from the group consisting of Au, Pd, and Ru, a 0.1-3.0 wt% second element selected from the group consisting of Cu, Ti, Cr, Ta, Mo, Ni, Al, Nb, Au, Pd, and Ru. The second element is different from the first element. The reflecting layer maintains the high optical reflection index of Ag. The reflecive layer has improved material stability and is stable when exposed to alkaline organic materials. The reflecting layer can be used as a reflector and a reflective wiring electrode for a liquid crystal display device, and as building glass for reflecting heat rays or infrared rays. IMAGE
