Blade for forming ribs in flat panel displays and its production method

摘要

One object of the present invention is to provide a blade (12) for forming ribs (23) that is able to improve wear resistance; in order to achieve the object, the present invention provide a blade (12) for forming ribs (23) that forms ribs (23) either on the surface of a substrate (10) or via an undercoating layer (22) on the surface of a substrate (10) by moving a blade body (12) in a fixed direction relative to a paste film (11) in the state in which comb teeth (12b) formed on at least a portion of the periphery of said blade body (12) are penetrated into said paste film (11) formed on the surface of said substrate (10) to plasticly deform said paste film (11); wherein, the surface of said comb teeth (12b) formed on said blade body (12) that makes contact with said paste film (11) is coated with a compound layer in which hard particles are dispersed in a metal. <IMAGE>
