摘要： A display device includes a pixel electrode including silver, a pixel-defining film on the pixel electrode and exposing the pixel electrode, a barrier layer on the pixel electrode and the pixel-defining film and including a low-resistance area and a high-resistance area which has a higher resistance than the low-resistance area, an emission layer on the barrier layer, and a common electrode on the emission layer. The low-resistance area of the barrier layer overlaps with the pixel electrode, and the high-resistance area of the barrier layer overlaps with the pixel-defining film.

摘要： A display device according to an embodiment includes: a first conductive layer that is disposed on a substrate; a transistor that is disposed on the substrate; and a light emitting element that is electrically connected to the transistor, wherein the transistor includes a semiconductor layer that at least partially overlaps the first conductive layer and is disposed on the first conductive layer, and a gate electrode that is disposed on the semiconductor layer. The semiconductor layer includes a first region that does not overlap the first conductive layer, a third region that overlaps the first conductive layer, and a second region that is disposed between the first region and the third region and traverses an edge of the first conductive layer. The first width of the semiconductor layer in the first region is smaller than a second width of the semiconductor layer in the second region.
