Abstract
Disclosed is an electromagnetic wave blocking member for a display apparatus. The electromagnetic wave blocking member may include a transparent substrate, an electrode layer, and a transparent conductive layer. The electrode layer can include i) a grounding electrode corresponding to at least one frame area of the transparent substrate, and ii) an auxiliary electrode overlying the transparent substrate for connection with the grounding electrode and having a mesh or stripe pattern. The transparent conductive layer can be formed either on the electrode layer or between the transparent substrate and the electrode layer. In one example, the transparent conductive layer can include a series of a metal thin film alternating with a metal oxide thin film a plurality of times.
