    Abstract: A display device includes at least one transistor. The transistor has an active pattern including a first active area and a second active area. The first active area includes a first channel area and an n-doped area contacting the first channel area. The second active area includes a second channel area and a p-doped area contacting the second channel area. A first insulation layer covers at least a portion of the active pattern. A first gate electrode is disposed on the first insulation layer and at least partially overlaps the first channel area. A second gate electrode is disposed on the first insulation layer and at least partially overlaps the second channel area. A taper angle of the second gate electrode is larger than a taper angle of the first gate electrode.

    Abstract: A method of manufacturing a display apparatus includes forming a first photosensitive pattern and a second photosensitive pattern of different thicknesses on an active layer; forming a driving semiconductor layer and a compensation semiconductor layer using the first photosensitive pattern and the second photosensitive pattern as masks to etch the active layer; exposing an upper surface of the driving semiconductor layer by etching the first photosensitive pattern and forming a third photosensitive pattern by etching at least a portion of the second photosensitive pattern; forming a first insulating layer on the driving semiconductor layer and the third photosensitive pattern; exposing an upper surface of the compensation semiconductor layer by stripping the third photosensitive pattern; and forming a second insulating layer on the first insulating layer and the compensation semiconductor layer.

    Abstract: A flexible display device includes a protection member, a first adhesion member, a display member, a second adhesion member, and a window member. A thickness of the display member is less than a sum of thicknesses of the protection member and the window member. The display member includes a display panel layer, a touch sensing layer, and a reflection prevention layer integrated with each other to reduce a thickness of the flexible display device. The reduction in thickness enables the flexible display device to be bent with a relatively small radius of curvature, as well as to be repeatedly bent (or otherwise flexed) with reduced potential for delamination of the first and second adhesion members.

    Abstract: A display device includes a first insulation layer on a first gate electrode, an active pattern on the first insulation layer and including an NMOS area and a PMOS area, the PMOS area overlapping the first gate electrode, a second insulation layer on the active pattern. The active pattern includes an NMOS area and a PMOS area, with the PMOS area overlapping the first gate electrode. In addition, a second gate electrode is on the second insulation layer and overlaps the NMOS area. An active-protecting pattern is in the same layer as the second gate electrode and passes through the second insulation layer to contact the PMOS area. A third insulation layer is on the active-protecting pattern and the second gate electrode. A data metal electrode passes through the third insulation layer and contacts the active-protecting pattern.

    Abstract: A flexible display device includes a display panel layer, a touch sensing layer, a reflection prevention layer, and a window layer. The touch sensing layer is disposed directly on a first display panel surface, a second display panel surface facing the first display panel surface in a thickness direction, or a second base surface of the reflection prevention layer. The reflection prevention layer is disposed directly on the second display panel surface or a first base surface of the touch sensing layer. The window layer is disposed directly on the first base surface or the second base surface.
