The plasma display device is known as a counter electrode type or a surface discharge type structurally, and a direct current type and an alternating current type are known in terms of applied voltage. For example, a monochrome plasma display device emits orange light by glow discharge in a sealed gas containing neon Ne, for example. A color plasma display device includes a discharge cell such as xenon X.
Ultraviolet rays are generated by glow discharge in a sealed gas containing e, and the ultraviolet rays cause the ultraviolet ray-excited phosphor applied to the inside of the transparent plate on the viewing side to emit light. In a color plasma display device, it is possible to emit monochromatic light of an arbitrary color by selecting an appropriate phosphor. For example, red, green, and blue phosphors are, for example, Y 2 O 3 : Eu, YVO 3 : for red.
