The invention discloses a display panel, a display device and a manufacturing method of the display panel, the display panel comprises a display substrate and a touch control layer arranged on the light-emitting surface of the display substrate, the display substrate is provided with a display area and a non-display area, the display substrate comprises a thin film transistor located in the display area and a driving line connected with the thin film transistor and extends to the non-display area, and the driving line is covered with an inorganic layer; and the touch layer comprises a touch electrode located in the display area and a signal line which is electrically connected with the touch electrode and extends into the non-display area, and at least part of the signal line is arranged on the inorganic layer. At least part of the signal lines are arranged on the inorganic layer, so that signal line patterning abnormity caused by the problems of poor adhesive force, etching abnormity and the like when the signal lines are directly formed on the organic layer is avoided, and the product quality is ensured.
Description
technical field [0001] The present application relates to the field of display technology, and in particular to a display panel, a display device, and a manufacturing method of the display panel. Background technique [0002] With the continuous development of technology, direct touch (Direct on cell touch, DOT) technology is more and more widely used in organic light-emitting semiconductor (Organic Light-Emitting Diode, OLED) display panels. DOT technology is to integrate the touch structure on the OLED display panel. Compared with the external touch display, the DOT display panel is lighter and thinner, and has better light transmittance and bending resistance. [0003] A patterned mask, namely a mask, is required in the manufacturing process of a DOT display panel. The existing DOT manufacturing process can be divided into a four-mask process and a two-mask process according to the number of masks used. The manufacturing process can be simplified by using the two-mask pr...
