    Abstract: A display device includes: a first display area including a first pixel circuit portion and a first light emitting element electrically connected each other; a 2-1 display area including a 2-1 pixel circuit portion, a 2-1 light emitting element electrically connected each other, and a 2-2 pixel circuit portion; and a 2-2 display area including a 2-2 light emitting element electrically connected with the 2-2 pixel circuit portion, and a light transmissive area. The first pixel circuit portion is disposed lower than the first light emitting element in a cross-sectional view, and the 2-1 pixel circuit portion is disposed lower than the 2-1 light emitting element in a cross-sectional view. The 2-2 light emitting element includes a first electrode, an emission layer, and a second electrode, and the 2-2 display area includes a low reflective layer that overlaps the first electrode in a plan view.
