Claim 0:
1. A micro-light-emitting diode display, comprising:
a driving substrate; and
a micro-light-emitting diode chip disposed on the driving substrate and comprising:
an epitaxial structure having a light exit surface, a back surface, and a sidewall surface, wherein the back surface is opposite to the light exit surface, and the sidewall surface is connected to the light exit surface and the back surface;
an electrode formed on the epitaxial structure and electrically coupled to the epitaxial structure;
a transparent structure having an inner surface and an outer surface, wherein the inner surface is connected to the sidewall surface, the outer surface is opposite to the inner surface, and a distance between the outer surface and the inner surface on a plane where the back surface is located is less than a distance between the outer surface and the inner surface on a plane where the light exit surface is located; and
a reflection layer in direct contact with the outer surface, wherein the micro-light-emitting diode chip is bonded on the driving substrate via the electrode, wherein the micro-light-emitting diode display comprises a plurality of the micro-light-emitting diode chips, the plurality of micro-light-emitting diode chips comprise a first micro-light-emitting diode chip and a second micro-light-emitting diode chip, and the outer surface of the transparent structure in the first micro-light-emitting diode chip has a smaller inclination angle than the outer surface of the transparent structure in the second micro-light-emitting diode chip.
