Abstract
A structure with micro light-emitting device includes a substrate, at least one micro light-emitting device, a holding structure, and at least one buffer structure. The micro light-emitting device is disposed on the substrate, and there is a vertical distance between the micro light-emitting device and the substrate. The holding structure is disposed on the substrate and directly contacts the micro light-emitting device. The buffer structure directly contacts the holding structure. Here, a Young's modulus of the buffer structure is smaller than a Young's modulus of the holding structure.
