Title:
LIGHT-EMITTING DIODE AND DISPLAY DEVICE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2022/097785
Kind Code:
A1
Abstract:
A light-emitting diode comprises: a first conductive semiconductor layer; an active layer on the first conductive semiconductor layer; a second conductive semiconductor layer on the active layer; a first electrode on the first conductive semiconductor layer; a second electrode on the second conductive semiconductor layer; and a diffusion layer between the first electrode and first conductive semiconductor layer. The first electrode comprises a plurality of layers, and one or more layers among the plurality of layers comprise a magnetic material. The diffusion layer comprises a magnetic material, and the thickness of the diffusion layer is 100nm or less. The ohmic characteristic of the diffusion layer is enhanced by changing the electrode structure mechanism such that the depth of the diffusion layer becomes 100㎛ or less. Also, during self assembly using a magnetic body, a luminance defect can be prevented and high luminance can be obtained by radically increasing the self assembly speed.
