## Abstract

A display panel, a fabricating method thereof, and an electronic device are provided. The display panel includes an array substrate; a color resist layer located on the array substrate; a light-emitting device layer located on the color resist layer; and a reflecting layer located between the color resist layer and the array substrate The reflecting layer reflects light emitted by the light-emitting device layer.
