LIGHT-EMITTING DEVICE

摘要

A light-emitting device includes a substrate that is capable of transmitting light, a conductive layer that includes a first conductive portion provided on the substrate and a second conductive portion which is provided on the substrate so as to be adjacent to the first conductive portion, The second conductive portion is thinner than the first conductive portion. A light emitting layer is provided on the first conductive portion. A first electrode is provided on the second conductive portion. A second electrode is provided on the light emitting layer. In some embodiments, a backside surface of the substrate may be processed to be optically rough so as to limit internal reflections.

1. A light-emitting device, comprising:
a transparent substrate having a first surface; a conductive layer including a first conductive portion on the first surface and a second conductive portion on the first surface, the second conductive portion being adjacent to the first conductive portion in a first direction along the first surface, the second conductive portion having a thickness in a second direction from the first surface that is less than a thickness in the second direction from the first surface of the first conductive portion; a light emitting layer on the first conductive portion, the light emitting layer including a first clad layer on the first conductive portion, an active layer on the first clad layer, and a second clad layer on the active layer; a first electrode on the second conductive portion; and a second electrode on the light emitting layer, wherein an outer peripheral surface of the first clad layer and an outer peripheral surface of the second clad layer are each disposed beyond an outer peripheral surface of the active layer in the first direction.
