Abstract
A method for producing a transferable array of light emitting devices includes forming a plurality of light emitting devices on a temporary substrate, forming at least one supporting member that is directly connected to a release layer of at least one of the light emitting devices, connecting a supporting substrate only with the at least one supporting member so that the at least one supporting member extends from the release layer of the at least one of the light emitting devices to the supporting substrate and so that the light emitting devices are spaced apart from the supporting substrate, and removing the temporary substrate. The transferable array produced by the method is also disclosed.
