Light-emitting device and projector

A light-emitting device, comprising:

• a substrate;
• a laminated structure provided at the substrate;
• a conductive layer provided at the laminated structure and configured to apply an electric current to the laminated structure;
• an insulating layer provided at the substrate and in contact with the conductive layer;
• and
• a first electrode provided between the laminated structure and the conductive layer, wherein
• the laminated structure is provided between the substrate and the conductive layer, and includes:
• a first semiconductor layer of a first conductive type;
• a second semiconductor layer of a second conductive type different from the first conductive type;
• and
• a light-emitting layer provided between the first semiconductor layer and the second semiconductor layer,
• the conductive layer includes a plurality of wire portions extending in a direction orthogonal to a lamination direction of the laminated structure, and is configured to polarize light generated at the light-emitting layer,
• an electric current is applied to the light-emitting layer via the plurality of wire portions,
• each of the plurality of wire portions is in contact with the first electrode, and
• as viewed from the lamination direction, the entire insulating layer is provided in a region other than a region where the conductive layer and the laminated structure are provided.
