| 1. A method of making a plasma display device, comprising:
providing a substrate on which a visible image is to be displayed;
providing a discharge sustain electrode over the substrate, the discharge sustain electrode being substantially transparent;
providing a first layer for a light-blocking layer over the discharge sustain electrode, the layer being substantially free
of a photosensitive material;
providing a second layer for a bus electrode over the light-blocking layer; and
selectively etching the second layer using photolithography so as to form the bus electrode; and
selectively etching the first layer so as to form the light-blocking layer.
