<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing reinforced plate glass by which glass surface strength can be sufficiently increased, and stable-quality reinforced plate glass is manufactured with high production efficiency, and to provide a reinforced plate glass manufactured by such manufacturing method. <P>SOLUTION: This reinforced plate glass 10 is composed of an inorganic oxide glass, and is provided with a compressive stress layer by chemical reinforcement on plate surfaces 11, 12 facing in the plate thickness direction. Plate end surfaces 13, 14, 15, 16 have regions where compressive stress is formed and regions where compressive stress is not formed. Each plate end surface has a surface formed by laser cutting. <P>COPYRIGHT: (C)2012,JPO&INPIT |
