Patent ID: 7573200

Claim:
A plasma display panel comprising: a front substrate and a back substrate that face each other with a space therebetween, the front substrate having a plurality of electrodes disposed on a main surface thereof, including a display electrode pair and an electron emitting electrode formed between the display electrode pair; and a dielectric film and a protective film formed sequentially to cover the electrodes, and luminescent display being performed by applying a voltage to the electrodes to cause a discharge in the space between the substrates, characterized in that: a plurality of needle crystals composed of a conductive substance or a semiconductor substance are disposed on the electron emitting electrode to reach the protective film by penetrating the dielectric film in a thickness direction from a surface of the electrodes, wherein the needle crystals are disposed substantially perpendicular to the main surface of the front substrate to penetrate the dielectric film in a thickness direction, and a material of the dielectric film and a material of the protective film are layered to completely fill gaps between the needle crystals.
