Abstract: A color conversion unit is provided. The color conversion unit includes a substrate and a color conversion layer. The substrate includes a hole. The color conversion layer is embedded in the hole of the substrate, wherein a ratio of a width to a height of the color conversion layer is between 1:1 and 1:15, and a color conversion mixture used to form the color conversion layer is cured by excitation light wavelength between 385 nm 1180 nm. A micro light-emitting diode disposed under the color conversion layer is used to provide light to the color conversion layer.
