Abstract

The embodiment of the invention discloses a display panel, a display device, a preparation method and a mask plate. The display panel comprises an array substrate, the array substrate comprises a substrate, a first wire and a second wire, the first wire and the second wire are located on one side of the substrate, a film layer where the first wire is located is located between the substrate and a film layer where the second wire is located, and orthographic projections of the first wire and the second wire on a plane where the substrate is located intersect with each other; the line width of the first wire at the projection overlapping position is smaller than the line width of at least part of the first wire at the non-projection overlapping position, and / or the line width of the second wire at the projection overlapping position is larger than the line width of at least part of the second wire at the non-projection overlapping position. According to the embodiment of the invention, the problem of line breakage caused by narrower line width due to excessive exposure at the projection overlapping position in the wiring of the existing display panel is solved, the wiring quality can be effectively ensured, the narrow frame design of the display panel is favorably realized, and the product competitiveness is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel, a display device, a manufacturing method, and a mask. Background technique [0002] The display panel is the main component for electronic equipment to realize the display function. A liquid crystal display panel is a display panel commonly used today. The liquid crystal display panel includes a display area and a frame area surrounding the display area. With the development of liquid crystal display technology, users have higher and higher requirements on the performance and appearance of the liquid crystal display panel, resulting in a smaller and smaller frame area of ​​the liquid crystal display panel. [0003] The frame area of ​​the display device is provided with wires, such as a fan-out (Fan-out) area, which is used to provide driving signals to the pixel units in the display area. Since the line width of the traces in the b...
