Abstract

An electronic device includes a first substrate, a plurality of light emitting elements each having a horizontal length and a vertical length which are less than or equal to about 10 micrometers (μm), each of the plurality of light emitting elements being disposed on the first substrate, a quantum dot color filter layer disposed on the plurality of light emitting elements, and a first overcoat layer between a plurality of light emitting elements and the quantum dot color filter layer. The quantum dot color filter layer includes a plurality of quantum dot color filters partitioned by a plurality of first partition walls so as to be overlapped with the plurality of light emitting elements, respectively.
