Abstract

The present application discloses a display panel, a display device, and a manufacturing method of the display panel. The display panel includes a display substrate and a touch layer disposed on the light-emitting surface of the display substrate. The display substrate has a display area and a non-display area. The thin film transistor in the display area, and the drive line connected with the thin film transistor and extending to the non-display area, the drive line is covered with an inorganic layer; the touch layer includes a touch electrode located in the display area, and is electrically connected to the touch electrode and The signal lines extending to the non-display area, at least part of the signal lines are arranged on the inorganic layer. By arranging at least part of the signal lines on the inorganic layer, when the signal lines are directly formed on the organic layer, abnormal patterning of the signal lines caused by problems such as poor adhesion and abnormal etching is avoided, and the quality of the product is guaranteed.

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 method for manufacturing 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. The DOT technology integrates 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, that is, a mask, is required in the manufacturing process of the 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 when the two-mask pr...
