Abstract
A display panel and a fabricating method thereof are provided. The fabricating method of the display panel has steps of: providing a substrate; forming a light conversion layer on the substrate, wherein material of the light conversion layer has a perovskite structural material with a chemical formula of ABX, wherein A represents an inorganic element, B represents an inorganic element, and X represents a halogen; performing a patterning step on the light conversion layer by an antisolvent method, wherein the light conversion layer forms a plurality of light conversion patterns; and forming a pixel layer on the light conversion layer, wherein the pixel layer has a plurality of pixel units, and the plurality of pixel units are respectively aligned with the plurality of light conversion patterns. The fabricating method can reduce a dark state brightness of the display panel, thereby improving contrast of the display panel.
