An electron emission element has an electron emission layer that emits an electron from a surface emission portion, a focusing electrode layer that is film-formed on a surface of the electron emission layer via a first insulation layer and focuses the emitted electron, a gate electrode layer that is film-formed on a surface of the focusing electrode layer via a second insulation layer, an emission concave portion that penetrates the gate electrode layer, the second insulation layer, the focusing electrode layer and the first insulation layer and opens in a concave shape on a surface of the surface emission portion, a carbon layer that is film-formed from a surface of the gate electrode layer over an inner peripheral surface of the emission concave portion, and a partial insulation portion that insulates the focusing electrode layer from the carbon layer.

A metal-made partition wallhas an external surface covered by an insulation layer, and transverse wallsA each extending in the row direction to define the partition between discharge cells C adjacent to each other in the column direction between a front glass substrateand a back glass substrateof a plasma display panel. A grooveAa formed in at least one of the front-facing face and the back face of the transverse wallA.

Partition-wall structure for plasma display panel and plasma display panel

Two substrates are placed opposite each other to form a hermetically sealed space between them. A metal-made partition wall is placed between the two substrates to partition the hermetically sealed space into unit light emission areas. Through holesAa are formed in a matrix arrangement in a portionA of the metallic partition wallopposite a display area portion of the back glass substrate. Dummy through holesBa are formed in a portionB of the partition wallopposite a non-display area portion of the back glass substrate. An insulating layercovers the outer surface of the partition wall

Display panel, method of manufacturing the display panel, and partition wall used in the display panel

A plasma display panel has row electrode pairs regularly arranged on a front glass substrate, a plurality of column electrodes regularly arranged in a row direction on a back glass substrate and each extending in a column direction to form discharge cells at the intersections with the row electrode pairs in a discharge space, and a partition wall positioned between the front glass substrate and the back glass substrate to define the discharge cells. The partition wall is constituted of a metallic base and a dielectric insulation layer covering the metallic base. An electrode for applying a direct-current potential is connected to the metallic base of the partition wall.
