The present invention provides a plasma display device, a light emitting device, and an image display system that are excellent in moving image quality and have a long lifespan. A plasma display panel including at least a substrate, a discharge gas space formed between the pair of substrates, an electrode formed on an opposite surface of the substrate, and a phosphor layer formed on a surface in contact with the discharge gas space of the pair of substrates; And afterglow time (1/10 afterglow) generated in each phosphor layer providing red, green, and blue light emission, which constitute a phosphor layer of a plasma display display device including a driving circuit for driving the panel through the electrode. Time) is 8 ms or less, and has a high performance under a vacuum ultraviolet region ultraviolet ray and a low-speed electron beam excitation [a divalent europium-activated alkaline earth silicate phosphor] composition formula (Ae) ac (Ae ') b Si x O y : A plasma display display and a light emitting device using Eu c . |
