Claim 0:
1. A growth substrate, comprising:
a substrate comprising a plurality of chip growth regions arranged at intervals and in an array, and a non-growth region located among the plurality of chip growth regions;
a refraction structure disposed on the substrate, an orthographic projection of the refraction structure on the substrate covering the non-growth region without overlapping with at least parts of the chip growth regions, wherein the refraction structure is configured to refract light corresponding to the non-growth region to positions corresponding to the chip growth regions;
wherein the substrate has a first surface and a second surface that are opposite to each other in a thickness direction of the substrate, and light emitting chips are grown in the chip growth regions of the first surface, wherein the refraction structure is disposed on the second surface, the orthographic projection on the substrate covers the non-growth region; and one side, away from the substrate, of the refraction structure is a light incident side.
