Abstract
A micro light emitting diode including an epitaxial structure and two electrodes is provided. The epitaxial structure includes a first surface, a second surface and a side surface. The first surface is opposite to the second surface, and the side surface is connected to the first surface and the second surface. The side surface includes a first portion and a second portion. The first portion is connected to the second portion to form a turning position. A width of the epitaxial structure gradually increases from the first surface to the turning position and gradually decreases from the turning position to the second surface. The two electrodes are disposed on the epitaxial structure and are electrically connected to the epitaxial structure. A micro light emitting diode device substrate adopting the micro light emitting diode is also provided.
