    Abstract: A thin film transistor substrate includes: a substrate, a first electrode disposed on the substrate, a bank disposed on the substrate and having an inclined surface inclined at an angle with respect to the substrate, a second electrode disposed on the bank, an active pattern electrically connected to the first electrode and the second electrode, disposed on the inclined surface, and including a first conductive region and a second conductive region in which impurities are doped, and a channel region between the first conductive region and the second conductive region, and a gate electrode overlapping at least a portion of the channel region of the active pattern. The inclined surface extends in a first direction in a plan view. The first conductive region, the channel region, and the second conductive region are sequentially disposed on the inclined surface along a second direction that crosses the first direction.

    Abstract: A display device according to the invention includes: a display panel and a driving chip mounted on the display panel. The display panel includes: a base layer, pixels, signal lines, fan-out lines, and a selection circuit. The base layer includes a first region, a second region bent with respect to a bending axis, and a third region adjacent to the second region. The pixels are arranged in the first region, and the signal lines are arranged in the first region and connected to the pixels. The fan-out lines are arranged in the second region and connected to the signal lines. The selection circuit is arranged between the fan-out lines and the driving chip in the third region and connected to the fan-out lines and the driving chip.

    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 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.
