摘要： There is provided a field emission display that can achieve high brightness without increasing the anode voltage, and can realize high resolution by suppressing the occurrence of inter-pixel crosstalk resulting from light excited from the phosphor layers. A field emission display is constructed by a field emission electron source disposed in a vacuum container and a phosphor screen that is disposed in the vacuum container so as to be opposite to the field emission electron source and that has a plurality of recessed portions on its surface opposing to the field emission electron source, with phosphor layers being formed in the recessed portions An image is displayed by causing the phosphor layers to emit light by collision of electrons emitted from the field emission electron source. The inner wall surface of the recessed portions widens in a tapered shape from the bottom surface side toward the opening side, and adjacent recessed portions are divided by a rib structure made of a material having a light-absorbing effect (Black effect) with respect to light of the light-emitting wavelength. The phosphor layers are formed substantially all over the bottom surface and-the inner wall surface of the recessed portions.

摘要： An electron beam emitted from a field-emission electron source array passes through a plurality of through holes formed in a mesh structure and reaches a target. Each of the plurality of through holes in the mesh structure has an opening on a side of the field-emission electron source array and an electron beam passageway that continues from the opening. The mesh structure is formed of a silicon-containing material doped with a N-type or P-type material. In this way, it is possible to suppress a decrease in the amount of the electron beam reaching the target while securing a mechanical strength of an electrode provided with a large number of through holes, and suppress expansion of the electron beam on the target.
