Abstract
The present invention relates to a substrate for the color conversion of a light-emitting diode and a manufacturing method therefor and, more specifically, to a substrate for the color conversion of a light-emitting diode and a manufacturing method therefor, which enable a quantum dot (QD) and a structure, in which the QD is supported, to have a color conversion function for implementing white light. To this end, the present invention provides a substrate for the color conversion of a light-emitting diode, comprising: a first glass substrate arranged on a light-emitting diode; a second glass substrate formed to face the first glass substrate; a structure arranged between the first glass substrate and the second glass substrate, having a hollow portion and formed from a mixture of a yellow phosphor and a low-melting point frit glass; a QD filling the hollow portion; and sealing materials respectively formed between the first glass substrate and the lower side of the structure and between the second glass substrate and the upper side of the structure.
