Planar plasma lamp and method of manufacture

A method of manufacturing a plasma lamp, comprising:

• screen printing a first phosphor layer on a broad face of a first planar lamp substrate;
• screen printing a second phosphor layer on a second broad face of a second planar lamp substrate;
• sealing the perimeters of the first and second broad faces together, wherein the first and second broad faces are positioned a separation distance apart;
• fabricating a first and second electrode, comprising:
• screen-printing a first and second buss electrode along the perimeter of a broad face of a first and second electrode substrate, the electrode substrates each comprising a glass plate coated on a broad face with a transparent conductive film comprising transparent conductive oxide, wherein screen-printing the first and second buss electrodes comprises:
• removing the transparent conductive oxide from perimeters of the glass plates;
• and
• screen-printing the first and second buss electrodes over the respective transparent film along the transparent film perimeter;
• joining the first electrode to a third broad face after fabricating the first electrode, the third broad face comprising an uncoupled broad face of the first substrate;
• and
• joining the second electrode to a fourth broad face after fabricating the second electrode, the fourth broad face comprising an uncoupled broad face of the second substrate.
