Abstract
Provided is a light-emitting apparatus which, without using an insulating film for separating pixels, inhibits leakage current between adjacent pixels and which accommodates higher resolution. By providing a groove in an insulating layer along an edge of a first electrode, the thickness of a first charge transport layer is reduced to inhibit leakage current between adjacent pixels.
