Abstract
A growth substrate and the display panel include a substrate, including chip growth regions arranged at intervals and in an array and a non-growth region located among chip growth regions. The growth substrate includes a refraction structure disposed on the substrate. An orthographic projection of the refraction structure on the substrate covers the non-growth region without overlapping with at least parts of the chip growth regions. The refraction structure is configured to refract light corresponding to the non-growth region to positions corresponding to the chip growth regions. The substrate has a first surface and a second surface and light emitting chips are grown in the chip growth regions of the first surface. The refraction structure is disposed on the second surface, an 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.
