In a front plate for PDP, which includes: 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 electrode; and 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, further, a large number of strip-shaped aid members for aiding formation of a dielectric layer are formed in a region located between the adjacent terminal groups. Thus, it is possible to make a circumference of a dielectric layer even although a dielectric material to be used is low in viscosity.
