Abstract: Disclosed herein are a micro LED structure and a micro LED projector. The micro LED structure comprises: a mesa structure and a reflective structure; wherein, the rays emitted from the sidewall of the mesa structure can be reflected by the reflective structure toward outside. The present disclosure can control the chief ray angle of the micro LED structure and reduce the loss of the light emitting from the sidewall of the mesa structure.
