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.

Abstract: The device includes a substrate, a green light emitting element on the substrate, and a green color film layer disposed on a light exit side of the green light emitting element correspondingly, a travel distance of the light emitted from the green light emitting element in the green color film layer remains substantially unchanged with a change of a light exit angle of the light. Thus, the present disclosure can prevent a color purity of a green light passing through the green color film layer from changing, thereby improving the color shift performance of a green light passing through the green color film layer, and improving the optical performance of the green light, and thus further improving the display effect of the device and the display panel.
