Abstract: A display panel and a display device are disclosed that enhance the aperture ratio of subpixels. The subpixels include first to fourth subpixels comprising first to third active patterns on the substrate. The first active pattern is electrically connected to the fourth signal line, the second active pattern is electrically connected to the second signal line or the third signal line, and the third active pattern is electrically connected to the first signal line, and at least one of the first to third active patterns includes a cutting area where the cutting areas of the first and second active patterns in the first and second subpixels overlap the emission area.

Abstract: The present disclosure provides a display device including a substrate including a plurality of subpixels each including a light-emitting area and a non-light-emitting area, an overcoating layer disposed on the substrate and having a plurality of micro-lenses including concave portions and connection portions in the light-emitting area, a first electrode disposed on the overcoating layer, a bank layer exposing a part of the first electrode on the overcoating layer and defining the light-emitting area, a light-emitting layer covering the first electrode exposed by the bank layer, and a second electrode disposed on the light-emitting layer. The bank layer may include a first bank area disposed adjacent to at least a part of the light-emitting area and having a first thickness, and a second bank area having a second thickness larger than the first thickness.

Abstract: A touch display device is disclosed that . has enhanced touch sensing accuracy in its periphery area. The touch display device comprises: a display panel including data lines, gate lines, subpixels, and touch electrodes that overlap a subpixel; a touch power circuit configured to generate and output a signal pulse width that is modulated; a gate driving circuit configured to supply a scan signal to the gate lines; a display controller configured to output a gate driving circuit control signal that controls controlling a driving timing of the gate driving circuit; a first line in a non-display area of the display panel that receives the gate driving circuit control signal; and a second line in the non-display area that receives the signal pulse width, wherein a width of the second line is larger than a width of the first line.
