Display device
Provided is a display device including a substrate, a transfer guiding mold provided on the substrate and including a plurality of openings, and a plurality of micro light emitting diodes (LEDs) provided on the substrate in the plurality of openings, wherein a height of the transfer guiding mold is less than twice a height of each of the plurality of micro LEDs.
1. A display device comprising:
a substrate;
a transfer guiding mold provided on the substrate and comprising a plurality of openings;
a plurality of micro light emitting diodes (LEDs) provided on the substrate in the plurality of openings,
wherein the transfer guiding mold is configured to guide a movement of the micro LEDs in a process of transferring the micro LEDs of the substrate,
wherein a height of the transfer guiding mold is less than twice a height, but greater than a single height, of each of the plurality of micro LEDs.
2. The display device of claim 1 , further comprising a plurality of driving circuits configured to drive the plurality of micro LEDs, respectively,
wherein each of the plurality of driving circuits are provided on the substrate and a portion of each of the plurality of driving circuits are exposed through the plurality of openings, respectively, of the transfer guiding mold.
3. The display device of claim 1 , wherein the plurality of micro LEDs are provided to be spaced apart from the transfer guiding mold.
4. The display device of claim 1 , further comprising a first reflective layer provided on the transfer guiding mold between the plurality of micro LEDs.
5. The display device of claim 1 , further comprising a second reflective layer provided on an inner wall of an opening provided in the transfer guiding mold.
6. The display device of claim 1 , further comprising a concave-convex structure provided on an upper surface of the transfer guiding mold.
7. The display device of claim 1 , further comprising a plurality of unit pixels each comprising a plurality of pixels of different colors.
8. The display device of claim 7 , wherein each of the plurality of unit pixels comprises two or more pixels of a same color.
9. The display device of claim 7 , wherein the plurality of pixels of different colors comprises a plurality of micro LEDs configured to emit light of different wavelength bands.
10. The display device of claim 7 , wherein the plurality of pixels of different colors comprises a plurality of micro LEDs configured to emit light of a same wavelength band, and at least some of the plurality of micro LEDs are provided with a photoconversion material layer configured to convert a wavelength of an incidence light.
11. The display device of claim 10 , further comprising a barrier provided on an upper portion of the transfer guiding mold, the barrier being configured to receive the photoconversion material layer.
12. The display device of claim 11 , further comprising a reflective layer provided on an inner wall of the barrier.
13. The display device of claim 11 , wherein a height of the barrier is greater than the height of the transfer guiding mold.
