Structure with micro device

An apparatus with micro device, comprising:

• a circuit substrate;
• at least one micro device, disposed on the circuit substrate and having 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, wherein the at least one micro device is electrically connected to the circuit substrate through the first-type electrode and the second-type electrode;
• and
• at least one light guide structure, disposed on the substrate, being away from the first-type electrode and the second-type electrode and comprising at least one connecting portion and a covering portion connected to the connecting portion, wherein the connecting portion is disposed on an edge of the top surface of the micro device, and an orthographic projection area of the light guide structure on the top surface is smaller than an area of the top surface.
