Abstract:
1. A method for producing a plasma display panel, comprising: forming a first layer by applying a first material for a lower electrode layer on a glass substrate; forming a second layer by applying a second material for an upper electrode layer on the surface of the first layer; and exposing to light a first part of the surface of the second layer, while shielding from light using a light-shielding member a second part of the surface of the second layer, and while shielding from light using a mask a third part of the surface of the second layer for portions of the first and second layers that are not to be formed into an electrode; developing such exposed portions of the first and the second layers to form an electrode, wherein a dimension T of the light-shielding member for shielding said second part of the surface in a direction parallel to a widthwise direction of the electrode fulfills 2 μm≦T≦10 μm and wherein the light shielding member is located such that an interval L between an end portion of the electrode in the widthwise direction, faulted after the exposure, and the end portion of the light-shielding member in the widthwise direction fulfills 1 μm≦L≦10 μm.
