Problems solved by technology

In this way, although the display failure phenomenon caused by cracks in the inorganic insulating layer is avoided to a certain extent, two Mask processes are added, which increases the difficulty of the process and the manufacturing cost, and reduces the production efficiency.
In addition, the formation of the connecting terminal bending area P needs to increase the space, and compared with the display products of the same size without the connecting terminal bending process, the utilization rate of the substrate substrate is lower for the display products manufactured using the connecting terminal bending process. Low

Abstract

The invention discloses a display panel and a manufacturing method thereof, and a display device. After a chip on film is adhered by adhesive to a side away from the display surface of a display substrate, signal lines around the display surface of the display substrate can be connected with connecting terminals arranged on the chip on film through a conductive material arranged in connecting holes which at least penetrate through the display substrate, the signal lines and an insulating layer. Thus, a connecting terminal bending process is omitted, there is no connecting terminal bending area around a display panel, and the display panel has a narrower bezel. Moreover, as the insulating layer is provided with multiple depressions around the connecting holes, the conductive material can be in contact with the surfaces of the signal lines in the depressions, the contact area of the conductive material and the signal lines is increased, hole drilling and conductive material filling failure are prevented, and the yield of the product is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a manufacturing method and a display device. Background technique [0002] With the continuous advancement of display technology, display panels are more and more widely used in display products. Display products with narrow bezels (Narrow Bezel) have attracted a large number of consumers because they can enable users to obtain a better viewing experience. [0003] Currently, bending the connection terminals is the only solution to realize display products with narrow bezels. However, there are many problems with the yield rate of the display products manufactured by the connecting terminal bending process. For example, in the Figure 1a The shown display products when bent, such as Figure 1b The inorganic insulating layer in the bending region P of the connecting terminal shown is prone to cracks, which will lead to display failure. In the prior art, a mask...
