Display device, electronic device, and fabrication method thereof

A method of fabricating a display panel, comprising

• preparing a substrate comprising a plurality of light emitting elements thereon and a first color conversion layer comprising first quantum dots, wherein each of the plurality of light emitting elements comprises semiconductor light emitting chip, and the first color conversion layer is disposed on a first light emitting element of the plurality of light emitting elements,
• forming a first photosensitive resin layer comprising a pigment, a dye, or a combination thereof of a first color on the first color conversion layer, and
• driving the first light emitting element on which the first color conversion layer is disposed to cure the first photosensitive resin layer with light emitted from the first light emitting element to form a first absorption-type color filter layer on the first color conversion layer.
