Abstract
Powder of a crystal body is disposed in positions respectively facing the discharge cells formed in the discharge space S defined between the front glass substrate and the back glass substrate of a PDP. The crystal body is included among an MgO crystal body having properties of causing CL (and PL) emission having a peak within a 200-nm to 300-nm wavelength range upon excitation by ultraviolet rays, and has properties of having a higher intensity of light emission caused by 146-nm wavelength ultraviolet light than the intensity of light emission caused by 172-nm wavelength ultraviolet light.
Claims8
A plasma display panel, comprising:
- a front substrate and a back substrate facing each other across a discharge space;
- row electrode pairs and column electrodes arranged between the front substrate and the back substrate to form unit light emission areas in positions in the discharge space respectively corresponding to intersections between the row electrode pairs and the column electrodes;
- and
- a dielectric layer covering the row electrode pairs,
- wherein powder of a crystal body is disposed in positions facing the unit light emission areas, is included among a magnesium oxide crystal body having properties of causing cathode luminescence emission having a peak within a wavelength range of 200 nm to 300 nm upon excitation by ultraviolet rays, and has properties of having a higher intensity of light emission caused by ultraviolet light at 146-nm wavelength than an intensity of light emission caused by ultraviolet light at 172-nm wavelength.
