Abstract

The invention provides a flexible circuit board, a manufacturing method thereof and a display device, and relates to the technical field of display. A wiring layer is arranged on a flexible substrate, a reinforcing layer is further arranged on the side, away from the wiring layer, of the flexible substrate, and the wiring layer comprises a plurality of signal wires distributed along a first wiring area, a second wiring area, a third wiring area and a fourth wiring area; the reinforcing layer comprises a first reinforcing structure located in the second wiring area and a second reinforcing structure located in the fourth wiring area. The first reinforcing structure is arranged in the second wiring area of the flexible substrate, and the second reinforcing structure is arranged in the fourth wiring area of the flexible substrate, so that the anti-impact strength of the flexible circuit board is enhanced, and therefore, when the display device is impacted, the flexible circuit board is not easy to tear, normal use of the display device is ensured, and the service life of the display device is prolonged. And the yield and the reliability of the display device are improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a flexible circuit board, a manufacturing method thereof, and a display device. Background technique [0002] In a display device, it is usually necessary to use an FPC (Flexible Printed Circuit, flexible circuit board) to realize the circuit connection between the display panel and a PCB (Printed Circuit Board, printed circuit board). [0003] At present, the flexible circuit board forms signal traces on the surface of one side of the flexible substrate. When the display device is impacted, the flexible circuit board is easily torn, so that the display device cannot be used normally. SUMMARY OF THE INVENTION [0004] The present invention provides a flexible circuit board, a manufacturing method thereof, and a display device, so as to solve the problem that the existing signal wiring is only formed on a flexible substrate, and the flexible circuit board is easily torn...
