Micro-led chip, reflective mirror layer for micro-led and method for forming the same, and photoresist ring

Abstract

The present invention relates to a reflective mirror layer for a micro-LED, and the reflective mirror layer is configured to reflect light from the light-emitting mesa toward the light extraction side, and the area of the upper surface of the light-emitting mesa facing the light extraction side is greater than the area of the lower surface facing away from the light extraction side, wherein the reflective mirror layer includes: a main body portion arranged to cover the lower surface of the light-emitting mesa and surround the side surface of the light-emitting mesa; and an edge portion connected with the edge of the main body portion and forming an angle greater than
