    摘要: The thin-type display device (1) has a transparent front wall (3), which is provided with a display screen, and a rear wall (24) which extends parallel to said front wall (3), and said display device comprises at least an electron source and a duct structure. The display device (1) is characterized in that the rear wall (24) and walls (22, 22', 22") of the ducts of the duct structure are manufactured in a single piece. Preferably, the walls (22, 22', 22") of the ducts widen in the direction of the rear wall (24), with the angle, which opposing faces of the walls (22, 22', 22") of the ducts make with each other, ranging from 1.degree. to 30.degree.. Preferably, the rear wall (24) further comprises at least an upright side wall (32), which is integral with the rear wall (24). Preferably, the walls (22, 22', 22") are made from a glass having a temperature interval between the operating temperature and the softening temperature of less than 420.degree., perferably less than 360.degree., and the duct structure and the side walls (32) can be pressed in one process step.
