Pixel circuit and display device, and a method of manufacturing pixel circuit

摘要

The display device including a pixel circuit has a first line, a transistor, a light emitting element, and a second line. The transistor is located between the second line and an electrode of the light emitting element. Either the first line or the second line is wired in a region that overlaps a light emitting region of the light emitting element in a lamination direction of layers. The second line intersects the first line outside of the light emitting region and overlaps a non-light emitting region of the light emitting element.
