Abstract
An apparatus with micro devices includes a circuit substrate, at least one micro device, and at least one light guide structure. The micro device is disposed on the circuit substrate. The micro device has a top surface and a bottom surface opposite to each other, a peripheral surface connected with the top surface and the bottom surface, a first-type electrode, and a second-type electrode. The light guide structure is disposed on the circuit substrate and is not in direct contact with the first-type electrode and the second-type electrode. The light guide structure includes at least one connecting portion and at least one holding portion. The connecting portion is disposed on an edge of the top surface of the micro device. An orthographic projection area of the light guide structure on the top surface is smaller than an area of the top surface.
