Abstract

A substrate, a method of preparing the substrate and a display device are provided. The substrate includes: a base substrate; a pixel defining layer on the base substrate, the pixel defining layer defining a plurality of opening regions arranged in an array, each of the plurality of opening regions having a plurality of sidewalls; and a barrier structure attached to at least one sidewall of at least one opening region. A distance from an upper surface of the barrier structure to the base substrate is less than a distance from an upper surface of the pixel defining layer to the base substrate, and at least a part of surfaces of the barrier structure are lyophobic.
