Description

technical field [0001] The present application relates to the field of display technology, in particular to a fan-out wiring structure and a display panel. Background technique [0002] The liquid crystal panel is an important component of the liquid crystal display device. With the cooperation of the backlight module and the drive of the driving circuit, the liquid crystal panel can display images. [0003] A TFT array area is arranged on the array substrate of the liquid crystal panel, and the TFT array area is covered with signal lines and TFTs. The driving circuit board connects the signal lines of the array substrate to the welding pins of the driving circuit board through fanout lines. The setting area of ​​the fan-out lines is called a fan-out area. [0004] Such as figure 2 As shown, the single-layer metal wiring structure of the existing fan-out area includes: a substrate 101, a plurality of first fan-out lines 102 arranged in parallel and spaced apart on the subs...
