Front plate for plasma display panel and method for manufacturing the same, as well as plasma display panel

A method for manufacturing a front plate for plasma display panel, the front plate including:

• a large number of display electrodes formed in stripes on a substrate;
• a plurality of terminal groups for connection with an external drive circuit, each terminal group being formed along an edge of the substrate, the edge being extended in a direction orthogonal to an extending direction of the display electrodes, the plurality of terminal groups including adjacent first and second terminal groups;
• a large number of lead electrodes extended from the display electrodes, respectively, in a non-image display region on the substrate to gather toward any one of the terminal groups without intersecting each other, the lead electrodes being connected to corresponding terminals in the relevant terminal group, respectively;
• and a large number of strip-shaped aid members for aiding formation of a dielectric layer formed in a region located between the adjacent first and second terminal groups;
• wherein the lead electrodes include a pair of lead electrodes facing each other across the region between the adjacent first and second terminal groups;
• and wherein the aid members include a first group of aid members that are formed generally in parallel with one of the pair of lead electrodes, and a second group of aid members that are formed generally in parallel with the other of the pair of lead electrodes,
• the method comprising forming the lead electrodes and the aid members simultaneously in such a manner that an electrode material containing a photosensitive material is exposed to light and is developed.
