1. A light emitting device, comprising:
a substrate;
a conductive layer disposed on the substrate;
a first reflective layer covering the conductive layer, the first reflective layer having an opening exposing a portion of the conductive layer;
a light emitting element disposed in the opening and electrically connected to the conductive layer;
a second reflective layer disposed on the first reflective layer and surrounding the light emitting element, the second reflective layer having an outer diameter, wherein a top surface of the second reflective layer is lower than a top surface of the light emitting element, wherein a height of the light emitting element is greater than a sum of heights of the first reflective layer and the second reflective layer; and
an encapsulating layer covering the light emitting element, a height between a highest point of the encapsulation layer and an upper surface of the first reflective layer being 0.1 to 0.5 times the outer diameter, wherein the encapsulating layer is in direct contact with the outer diameter of the second reflective layer.
