Abstract

A light-emitting device or a display device that is less likely to be broken is provided. Provided is a light-emitting device including an element layer and a substrate over the element layer. At least a part of the substrate is bent to the element layer side. The substrate has a light-transmitting property and a refractive index that is higher than that of the air. The element layer includes a light-emitting element that emits light toward the substrate side. Alternatively, provided is a light-emitting device including an element layer and a substrate covering a top surface and at least one side surface of the element layer. The substrate has a light-transmitting property and a refractive index that is higher than that of the air. The element layer includes a light-emitting element that emits light toward the substrate side.
