A display device comprises a first substrate including a plurality of pixels, a plurality of light emitting diodes (LEDs) in each of the plurality of pixels, a plurality of light conversion units on the plurality of LEDs, and a plurality of partitions configured to surround each of the plurality of light conversion units. Each of the plurality of light conversion units is in a groove inside the plurality of partitions.

Display device

Embodiments of the present disclosure relate to a transfer head assembly and an LED transfer apparatus, and more particularly, to a transfer head assembly and an LED transfer apparatus in which a plurality of pickup units picks up LEDs, which are adhered to the upper surfaces of the LEDs, and transfers the LEDs to a display substrate. According to the embodiments of the present disclosure, a large number of LEDs located on a wafer substrate or a carrier substrate can be transferred in bulk to a display substrate. Thus, it is possible to rapidly perform the transfer process of the LEDs.

Transfer head assembly and LED transfer apparatus

Provided is a display device. The display device includes a substrate having a sub-pixel area. In some examples, the substrate may have or define a plurality of sub-pixel areas. A light-emitting diode (LED) and a thin-film transistor for driving the LED are disposed in the sub-pixel area. An extended light path layer is disposed on the substrate and is configured to surround the sub-pixel area. Accordingly, it is possible so as to improve the luminous efficiency of the display device.
