Abstract
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 holes 20Aa are formed in a matrix arrangement in a portion 20A of the metallic partition wall 20 opposite a display area portion of the back glass substrate 4. Dummy through holes 20Ba are formed in a portion 20B of the partition wall 20 opposite a non-display area portion of the back glass substrate 4. An insulating layer 20a covers the outer surface of the partition wall 20.
Claims10
A display panel comprising:
- first and second substrates placed opposite each other to form a hermetically sealed space between them;
- a resin layer formed on the first substrate;
- and
- a metal plate covered with an insulating layer, and fixed onto an inner surface of the first substrate by the resin layer, and having a plurality of formed-for-unit-light-emission-area through holes formed in a matrix arrangement in a portion of the metal plate opposite a display area portion of the first substrate for formation of unit light emission areas, and burning-process-use through holes formed in a portion of the metal plate opposite a non-display area portion of the first substrate to function in a burning process.
A method of manufacturing a display panel, comprising the steps of:
- forming a resin layer on an inner surface of a first substrate of first and second substrates which are placed opposite each other to form a hermetically sealed space between the two substrates;
- arranging, on the resin layer formed on the first substrate, a metal plate covered with an insulating layer and having a plurality of formed-for-unit-light-emission-area through holes formed in a matrix arrangement in a portion opposite a display area portion of the first substrate for formation of unit light emission areas, and burning-process-use through holes formed in a portion opposite a non-display area portion of the first substrate to function in a burning process;
- and
- burning the first substrate, having the metal plate arranged thereon, to fix the metal plate onto the first substrate by the resin layer.
A display-panel-use partition wall made of metal and placed between two first and second substrates, arranged opposite each other with a hermetically sealed space in between, to partition the hermetically sealed space into unit light emission areas, the display-panel-use partition wall comprising:
- formed-for-unit-light-emission-area through holes formed in a matrix arrangement in a portion of a metal plate opposite a display area portion of the first substrate for formation of the unit light emission areas;
- burning-process-use through holes formed in a portion of the metal plate opposite a non-display area portion of the first substrate to function in a burning process;
- and
- an insulating layer covering an outer surface of the display-panel-use partition wall.
