Display panel and method of manufacturing the display panel

摘要

Two substrates are placed opposite each other to form a hermetically sealed space between them. A metal-made partition wall (20) 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. 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. An insulating layer covers the outer surface of the partition wall (20).
