A light-emitting diode (LED) packaging structure and a substrate for the packaging structure are provided. The light-emitting diode packaging structure includes a metal substrate having a first surface and a second surface opposite to the first surface, and the first surface has a concave portion with a sidewall and a bottom, allowing an anode film to be formed on the metal substrate; a plurality of electrically conductive pads formed on the bottom of the concave portion; an optical treatment layer formed on the sidewall of the concave portion; and an LED die mounted on the bottom of the concave portion and electrically connected to the electrically conductive pads. Desired electrical insulating property between any two adjacent electrically conductive pads can be obtained by the anode film formed on the metal substrate, while a good thermal conductivity of the metal substrate is maintained.
