Abstract

The invention provides a display panel and a manufacturing method thereof. The display panel is provided with a bending area and a non-bending area, and comprises a flexible substrate, a first routinglayer, an insulating layer and a second routing layer which are arranged in a laminated mode. The first routing layer comprises a plurality of first routings; at least two via holes penetrating the insulating layer are formed in the insulating layer corresponding to each first routing, and the via holes are formed at the positions close to the non-bending areas at two ends of the bending area; the second routing layer comprises a plurality of second routings; the second routings and the first routings are arranged in one-to-one correspondence; and the second routings extend and pass through the via holes to be electrically connected with the first routings. The manufacturing method of the display panel comprises the following steps of: providing a flexible substrate, manufacturing a firstrouting layer, manufacturing an insulating layer and manufacturing a second routing layer. The display panel and the manufacturing method thereof solve the problem that a metal electrode is cracked or broken in the bending area.

Description

technical field [0001] The invention relates to the display field, in particular to a display panel and a manufacturing method thereof. Background technique [0002] In the current mobile terminal market, the design requirements for high screen-to-body ratio are getting higher and higher; how to compress the borders of the non-display area in the design of LCD screens has become the focus of design by various manufacturers. The design of folding the non-display area to the side or back of the display has become a hot spot in the current high screen-to-body ratio design. [0003] Flexible liquid crystal display is bendable because the substrate material of thin film transistor (TFT) and color filter substrate (CF) is made of soft materials such as polyimide (PI) or polyethylene terephthalate (PET). , deformation, it is easier to realize the inflection of the non-display area, but the metal electrode of the existing design is one layer, and it is easy to cause the metal elect...
