Abstract
The present disclosure relates to the field of display technology, and proposes a display panel, a preparation method thereof, and a display apparatus. The display panel includes an array substrate, a planarization layer group, and a plurality of sub-pixels. The array substrate includes a switch array formed by a plurality of switch units. The planarization layer group is provided on the array substrate, and nano-scale grooves are provided on the planarization layer group. The sub-pixels are provided on a side of the planarization layer group away from the array substrate. The sub-pixel includes a plurality of first electrodes, wherein the first electrode is connected to the switch unit of the array substrate, a nano-scale second gap is provided between two adjacent first electrodes, and an orthographic projection of the second gap on the array substrate is located within an orthographic projection of the groove on the array substrate.
