Abstract: A display device includes a substrate including a first recess portion, a semiconductor layer that overlaps the first recess portion, the semiconductor layer including protrusions and depressions conforming to a shape of the first recess portion, and a gate electrode that overlaps the first recess portion and the semiconductor layer, the gate electrode including protrusions and depressions conforming to the shape of the first recess portion. A thickness of the substrate in the first recess portion is less than a thickness of the substrate in a non-recess portion, excluding the first recess portion.

Abstract: A display device includes a substrate, a first thin-film transistor (TFT), a first organic light-emitting diode (OLED), and a second OLED. The TFT is on a first surface of the substrate and includes a first output electrode and a second output electrode. The OLED is on the first surface of the substrate and is electrically connected to the first output electrode of the TFT. The second OLED is on a second surface of the substrate and is electrically connected to the second output electrode of the TFT.

Abstract: A display device includes a peripheral area around a display area, a display element in the display area, and a dam in the peripheral area. A thin film encapsulation layer covers the dam and the display element. A touch sensor is on the thin film encapsulation layer. A first insulating layer is between the thin film encapsulation layer and the touch sensor and has a first region and a second region. A dielectric constant of the first region is lower than a dielectric constant of the second region, and the first region is between the dam and the touch sensor.
