The utility model provides a light-emitting diode (LED) circuit structure. First cutout performed a substrate forms plural first cutout regions and plural first material regions. Second cutout performed on the substrate forms plural second cutout regions, plural third cutout regions, plural second material regions, and plural third material regions. Besides, a second adhering layer is adhered to another side, which is opposite to the substrate, of the first adhering layer; a heat dissipation layer is adhered to another side, which is opposite the first adhering layer, of the second adhering layer. Accordingly, such the LED circuit does not require conventional electroplating, etching, and washing processes, and further not only the effect of saving energy and reducing carbon emission can be achieved, but also the effect of being flexible, reducing a manufacturing time and reducing manufacturing costs can be achieved.
