Method for producing a light emitting device
First Claim
1. A production method for producing a light-emitting device in which a light-emitting layer at least including a n-type semiconductor layer and a p-type semiconductor layer is layered on a transparent crystal substrate, comprising the steps of:
- forming a transfer layer on at least a part of the transparent crystal substrate or the light-emitting layer, which transfer layer is softened or set upon supplying an energy thereto;
pressing a mold formed with a minute unevenness structure against the transfer layer to transfer the minute unevenness structure to an outer surface of the transfer layer; and
forming a minute unevenness structure for preventing multiple reflection based on the minute unevenness structure transferred to the transfer layer.

Abstract
A production method for producing a light-emitting device 1 in which a light-emitting layer at least comprised of a n-type substrate bearing layer 3 and a p-type substrate bearing layer 4 is layered on a transparent crystal substrate 2 is provided with a step of forming a transfer layer 5 on at least a part of the transparent crystal substrate 2 or the light-emitting layer 3, 4, which transfer layer 5 is softened or set upon supplying an energy thereto; a step of pressing a mold 6 formed with a minute unevenness structure 61 against the transfer layer 5 to transfer the minute unevenness structure 61 to an outer surface of the transfer layer 5, and a step of forming a minute unevenness structure 21, 34 for preventing multiple reflection based on the minute unevenness structure 51 transferred to the transfer layer 5.
