Display panel and display device

Abstract

The invention provides a display panel and a display device. The display panel includes a display area, a wiring fan-out area and a bending area, wherein the wiring fan-out area comprises multiple signal wires which comprise at least first wiring and second wiring arranged mutually parallelly; the first wiring is formed by connecting a first metal section and a first gate layer; the second wiring is formed by connecting a second metal section and a second gate layer; the resistance values of the first metal section and the second metal section are smaller than those of the first gate layer and the second gate layer; and the length of the first metal section is smaller than that of the second metal section. The display device comprises the above display panel. Linear wiring is adopted to replace Z-type wiring, a large number of corner positions do not exist, and the risk of short circuit at the wiring corner position is avoided; and through adjusting the length of the metal layer forming each piece of linear wiring, the resistance of the wiring at different positions is balanced, and the uniformity of display is ensured.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel and a display device. Background technique [0002] With the development of technology in the display industry, customers have higher and higher requirements for display panels. For some high-end display panels, customers will require narrow bezel designs. [0003] Such as figure 1 As shown, it is a schematic diagram of the display area and the lower frame structure of an existing active matrix organic light emitting diode (AMOLED) display panel. The existing display panel includes a display area 100, a wiring fan-out area 200 and a bending area 300. In this structure, in order to converge the vertical alignment of the larger width of the display area 100 into the narrower width range of the bending area 300, the vertical alignment on both sides of the display area 100 is converged toward the center, thus producing The difference in the length of the wires at the mid...

Problems solved by technology

[0004] like figure 2 shown, for figure 1 The cross-sectional view of the wiring fan-out region 200 in the above sequence includes the substrate 201, the first gate layer 202, the dielectric layer 203, the second gate layer 204, the insulating layer 205 and the metal layer 206, but this kind The second gate layer 204 designed at the corner position 210 of the Z-shaped wiring has a phenomenon that the taper on one side is too large, so that the second gate layer 204 is not completely covered by the insulating layer 205, resulting in The metal layer 206 on the subsequent insulating layer 205 is short-circuited with the second gate layer 204, which eventually leads to abnormal display of the product
