1. A light-emitting display device based on special-shaped nLED grains, comprising an upper drive electrode substrate, an upper drive electrode, special-shaped nLED grains, a lower drive electrode and a lower drive electrode substrate that are sequentially arranged from top to bottom, and being further provided with an AC drive control module having two ends connected to the upper drive electrode and the lower electrode respectively, wherein the special-shaped nLED grains are nLED grains each comprising a non-planar luminous layer, and at least part of the luminous layers are perpendicular to an electric field no matter in which direction the nLED grains are regularly disposed between the electrode substrates; and the drive electrode is isolated from the nLED grains by an insulating dielectric layer, and in presence of the AC drive signal, the nLED grains are lighted up through electromagnetic coupling.
