Panel for discharging within cells positioned on a pair of line electrodes

A discharge panel capable of high-quality display by preventing erroneous discharge between adjacent lines in a sustaining electrode or the like. A sectional shape in a direction orthogonal to the longitudinal directions of both a first display electrode ( 101 a) and a second display electrode ( 101 b) has a stepped shape, a film thickness of a discharge gap (Gap 1 ) side portion is greater than that on a non-discharge gap side, the film thickness of the respective steps being specified as L 1 , L 2 , L 3 (L 1 >L 2 >L 3 ). Accordingly, a discharge start voltage on the discharge gap side is lower than that on the non-discharge gap side even when the discharge gap and the non-discharge gap have the same width geometrically, thereby reducing erroneous discharge between adjacent cells positioned on an adjacent lines.
