Abstract
A circuit board for a light-emitting diode assembly according to an embodiment includes a substrate layer having a first surface and a second surface facing each other, a conductive circuit layer disposed on the first surface of the substrate layer and having a single-layered structure, and an insulating layer formed on the first surface of the substrate layer to cover the conductive circuit layer. Channel resistance, luminous efficiency and luminous uniformity can be improved through a side connection of a dimming zone while vias or contacts are omitted.
