Abstract
A plasma display panel with an increased display contrast improves a visibility of the display at low costs. A green light absorbing filter is provided on the outer surface of a substrate on the display surface side and a monochromatic light transmitting filter corresponding to at least one of red and blue fluorescent material layers which face each other through a discharge space is provided on the inner surface of the substrate on the display surface side. The green light absorbing filter is provided on the outer surface of the substrate on the display surface side and at least one of the red and blue fluorescent material layers is formed by a fluorescent material layer colored so as to absorb the light in wavelength regions other than the corresponding monochromatic light.
