Patent ID: 7453197

Claim:
A display apparatus comprising: a first plate-shaped member having a plurality of electron-emitting devices which are dispersively distributed; and a second plate-shaped member having a plurality of light-emitting members arranged on a surface which faces said first plate-shaped member in correspondence to said plurality of electron-emitting devices, in which, in at least either said first plate-shaped member or said second plate-shaped member, directions of normal lines extending from said plurality of electron-emitting devices or said plurality of light-emitting members are distributed in a tendency, wherein a pitch between at least one of the electron-emitting devices and an electron-emitting device adjacent to that at least one electron-emitting device and a pitch between a light-emitting member corresponding to the at least one electron-emitting device and a light-emitting member adjacent to the at least one light-emitting member are different so that an electron emitted from each of said plurality of electron-emitting devices is irradiated to each of said plurality of corresponding light-emitting members, wherein each of said first plate-shaped member and said second plate-shaped member has a convex shape having a radius of curvature R which is projected in the direction directing from said second plate-shaped member to said first plate-shaped member, a neutral plane of said first plate-shaped member and a neutral plane of said second plate-shaped member are located at a distance T, and the pitch of arranging said electron-emitting devices is 1+T/R times as large as the pitch of arranging said light-emitting members.
