Method of manufacturing PDP bus electrode

A method of manufacturing a PDP bus electrode comprising steps of:

• (a) applying onto a glass substrate a black paste comprising, based on the weight of the black paste,
• (i) 6 to 20 wt % of a black colorant,
• (ii) 15 to 32 wt % of a first glass frit having a first softening point,
• (iii) 1 to 10 wt % of a second glass frit having a second softening point,
• (iv) 1 to 10 wt % of a photopolymerization initiator,
• (v) 6 to 18 wt % of a photopolymerizable compound, and
• (vi) 20 to 60 wt % of an organic medium;
• (b) applying a white paste onto the applied black paste;
• (c) exposing the applied black paste and the applied white paste on the glass substrate to light;
• (d) developing the exposed black paste and the white paste;
• and
• (e) firing the developed black paste and the developed white paste with a firing profile having a firing peak temperature to form a black electrode and a white electrode respectively,
• wherein the first softening point of the first glass frit is lower than the firing peak temperature and wherein the second softening point of the second glass frit is higher than the firing peak temperature.
