Abstract
A light emitting apparatus includes a substrate; a light emitting device disposed on the substrate and configured to generate light; a second light-transmitting layer disposed on the substrate so that light generated from the light emitting device is transmitted therethrough; a first reflective layer disposed between the substrate and the light emitting device; and a second reflective layer disposed on the substrate and configured to reflect light toward the second light-transmitting layer, wherein the second reflective layer includes 20 wt % to 70 wt % of aluminum and 10 wt % to 60 wt % of oxygen.
