Claim 18:
19. The preparation method according to claim 18, wherein sequentially forming the passivation layer and at least one second electrode on the side, away from the base, of the flat layer comprises:
forming passivation material layers on the side, away from the base, of the flat layer and the side, away from the base, of the first electrode;
forming at least one second electrode on the side, away from the base, of the passivation material layer by a patterning process, wherein a front projection of the second electrode on the base is adjacent to or partially overlaps with the front projection of an adjacent first electrode on the base; and
removing the passivation material layer on the side, away from the base, of the first electrode through dry etching by a self-alignment process to obtain the passivation layer.
