Kind Code:
A1
Abstract:
Disclosed is an image display device wherein the concentration of an electric field at the portion of a spacer (10), which faces a face plate, can be relieved. The spacer covers an area (31) provided with an anode and an area which is not provided with an anode, and is located between the face plate and a rear plate. The spacer is provided with a plurality of conductive members (14) on the side surface thereof. The conductive members (14) extend through the portions of the spacer, which overlap with the area provided with an anode and the area which is not provided with an anode, and the distances between the conductive members and the face plate are different from one another. The end portions of the conductive members are provided in the portions of the spacer, which overlap with the area provided with an anode and an area which is not provided with an anode. The end portion of the conductive member farthest from the face plate is farthest from the anode (12).
