A thin glass substrate and a flat panel display (FPD) including the same. The thin glass substrate includes a transparent base member and a transparent mesh pattern formed on one surface of the base member. The base member may be stably supported by the mesh pattern and tension is provided when the base member is deformed so that it is possible to prevent the base member from being broken. In addition, the mesh pattern disperses shock or stress applied to the base member, and it is possible to suppress electromagnetic wave interference from the outside.
