ABSTRACT:
A discharge chamber wherein the allowability for positional displacement of electrodes is increased to facilitate manufacture of the discharge chamber and a method of manufacturing the discharge chamber are disclosed. The discharge chamber has a flat panel structure wherein a first substrate and a second substrate are adhered to each other with a predetermined gap left therebetween. Striped anodes and cathodes are arranged alternately on the first substrate. Barrier ribs are interposed between the two substrates and arranged in a stripe pattern to partition the gap to form discharge channels. The anodes are arranged just below the barrier ribs and have a width dimension smaller than the width dimension of the barrier ribs. Meanwhile, each of the cathodes is arranged intermediately between each adjacent ones of the cathodes. Even if the barrier ribs suffer from relative positional displacement, the exposed surface area of the cathodes by which plasma discharge is dominated is kept fixed.
