Abstract
A light-emitting apparatus includes a substrate, pads disposed on the substrate, a sacrificial pattern layer and a light-emitting diode element disposed on the sacrificial pattern layer. The light-emitting diode element includes a first type semiconductor layer, a second type semiconductor layer, an active layer, and electrodes. A connection patterns disposed on at least one of the electrodes and the pads. Materials of the connection patterns include hot fluidity conductive materials. The connection patterns cover an outermost sidewall of the sacrificial pattern layer and are electrically connected to the at least one of the electrodes and the pads. The sacrificial pattern layer is located between the connection patterns, and the sacrificial pattern layer is overlapped with the pads in a normal direction of the substrate.
