Abstract
The present application discloses an array substrate comprising a first substrate, a first electrode on the first substrate, a passivation layer on a side of the first electrode distal to the first substrate, the passivation layer comprising a plurality of first vias, each of which corresponds to a different part of the first electrode, an electron emission source layer on a side of the first electrode distal to the first substrate comprising at least one electron emission source in each of the plurality of first vias, and a dielectric layer on a side of the first electrode distal to the first substrate comprising a plurality of dielectric blocks corresponding to the plurality of first vias, at least a portion of each of the plurality of dielectric blocks in each of the plurality of first vias. The at least one electron emission source comprises a first portion having a first end and a second portion having a second end. The first end is in contact with the first electrode, the first portion is within a corresponding one of the plurality of dielectric blocks. The second portion and the second end are outside the corresponding one of the plurality of dielectric blocks.
