US 2026/0259456 A1 · DISPLAY SUBSTRATE AND PREPARATION METHOD THEREOF, DISPLAY PANEL AND DISPLAY APPARATUS

Abstract

A display substrate and a preparation method thereof, a display panel, and a display apparatus are provided, which relate to the technical field of a display. The display substrate includes a base substrate and a plurality of support pillars disposed on a side surface of the base substrate, and the support pillars have a first surface close to the base substrate and a second surface opposite to the first surface. In any direction parallel to the substrate, a ratio of a width of the first surface to a width of the second surface is greater than or equal to 0.8, and less than or equal to 1.2, and the width of the first surface is greater than or equal to 0.8 micrometers and less than or equal to 3 micrometers.
