Abstract:
1. A method for manufacturing electrodes of a plasma display panel, comprising: providing a rear transparent substrate; coating a photosensitive conductive paste film of negative-working type on the rear transparent substrate; performing an exposure process for exposing the photosensitive conductive paste film to define a plurality of address electrodes on the rear transparent substrate, wherein a first exposure energy acting on a plurality of main regions of the address electrodes is greater than a second exposure energy acting on a plurality of edge regions of the address electrodes; performing a development process to develop the exposed photosensitive conductive paste film to form the address electrodes, in which a first thickness of the edge regions of the address electrodes is less than a second thickness of the main regions of the address electrodes; and performing a firing process to fire the developed photosensitive conductive paste film.
