An exhaust hole (10) formed in a cathode substrate (1) is surrounded by an exhaust substrate (6), an exhaust substrate frame (71), and a sealing material (32) so that an exhaust chamber is formed. An exhaust substrate exhaust hole (81) is formed in the exhaust substrate (6), and an exhaust tube (8) is connected to the exhaust substrate exhaust hole (81) to evacuate an interior of a display device. If an end part of the exhaust hole (10) has a sharp edge, sparking will start to occur at the edge. To address this problem, a chamfer (101) is formed on the exhaust hole (10). Similarly, chamfers may be formed on the exhaust substrate exhaust hole (81) and a high-voltage introduction button hole (82). Forming such chamfers can prevent sparking originating from the edges of the exhaust hole (10) and the like formed in the cathode substrate (1) and the like.
