Light emitting apparatus

摘要

A light emitting apparatus includes a plurality of single crystal semiconductor thin films that emit light. The single crystal semiconductor thin films are secured in intimate contact to the surface of a substrate or a bonding layer formed on the substrate. A first conductive electrode is formed on the single crystal semiconductor thin film and is connected to a first conductive side metal layer. The first conductive side metal layer is closer to the surface of the substrate than a top surface of the single crystal semiconductor thin film. A second conductive electrode is formed on the single crystal semiconductor thin film. A second conductive side metal layer is connected to the second conductive electrode. The second conductive side metal layer is closer to the surface of the substrate than the top surface of the single crystal semiconductor thin film.

1. A light emitting apparatus comprising:
a substrate; a plurality of single crystal semiconductor thin films formed on a surface of the substrate, each of the single crystal semiconductor thin films emitting light when current is passed therethrough; a common electrode in contact with top surfaces of the plurality of single crystal semiconductor thin films, the common electrode covering the plurality of single crystal semiconductor thin films from above, the common electrode being electrically conductive and transparent to the light emitted from the plurality of single crystal semiconductor thin films; and a common wiring including a plurality of openings formed therein so that each of the single crystal semiconductor thin films is in a corresponding one of the openings, the common wiring being lower than said top surfaces and being directly connected to the common electrode, the common wiring being electrically conductive and blocking the light emitted from the plurality of single crystal semiconductor thin films, when viewed perpendicularly to the substrate, the common wiring forms a closed shape around at least one of the single crystal semiconductor thin films so that the at least one of the single crystal semiconductor thin films is within the closed shape.
