    Abstract: A display device is disclosed that includes a substrate, a semiconductor layer, a first conductive layer, and a first gate insulating layer. The semiconductor layer is disposed on the substrate and includes a first area and a second area. The first conductive layer is disposed on the semiconductor layer and includes a first gate pattern overlapping the first area and a second gate pattern overlapping the second area. The first gate insulating layer is disposed between the semiconductor layer and the first conductive layer and includes a first insulating layer overlapping the first area and the second area, a second insulating layer overlapping the first area and the second area, and a third insulating layer not overlapping the first area but overlapping the second area. The second insulating layer is disposed between the first insulating layer and the third insulating layer, and has a dielectric constant greater than that of the third insulating layer.

    Abstract: A display device includes a substrate and a display element layer on the substrate. The display element layer includes: first and second electrodes extending along a first direction and spaced apart from each other in a second direction; and light emitting elements electrically connected to the first and second electrodes. The first electrode has a first convex portion convex toward the second electrode and a first concave portion concave in a direction away from the second electrode, and the second electrode has a second convex portion convex toward the first electrode and a second concave portion concave in a direction away from the first electrode. The light emitting elements includes a first and second light emitting elements, respectively close to the first concave portion and the second concave portion based on an imaginary extension line extending in the first direction between the first electrode and the second electrode.
