In this arrangement, the support member is made of an insulating material, and of a plurality of electron-emitting devices arranged substantially linearly, two electron-emitting devices adjacent to each other through the support member are arranged at a larger interval than the interval between two electron-emitting devices adjacent to each other without the mediacy of the support member.
