Abstract:
A surface-discharge type display device comprising:a first panel including a first substrate and a plurality of electrode pairs which are aligned on a main surface of the first substrate and are each made up of a first electrode and a second electrode; and a second panel including a second substrate, a plurality of electrodes aligned on a main surface of the second substrate, and a plurality of barrier ribs aligned on the main surface of the second substrate, the second panel being placed parallel to the first panel with the plurality of barrier ribs being interposed in between, so that the plurality of electrodes face the plurality of electrode pairs, a discharge gas being enclosed in discharge spaces which are formed between the first panel and the second panel and are separated from each other by the plurality of barrier ribs, and the surface-discharge type display device producing an image display by using a surface discharge induced between the first and second electrodes, wherein the first and second electrodes are coated with a first dielectric layer, and an area that has a lower relative permittivity than the first dielectric layer is formed in an area surrounded on three sides by the first electrode, the second electrode, and the first substrates, wherein a second dielectric layer which is different from the first dielectric layer is formed in the area surrounded on three sides by the first electrode, the second electrode, and the first substrate, the second dielectric layer having a lower relative permittivity than the first dielectric layer.
