Problems solved by technology

[0003] However, the narrow frame and frameless design makes the conductive area left by the display device for the display panel smaller. Small, resulting in a small contact area between the Bonding pad and COF (Chip On Film, chip-on-film), which reduces the conductivity of the Bonding pad and its connection stability with COF

Abstract

The invention discloses a display panel, a manufacturing method thereof and a display device. A designed bonding pad comprises a first conductive bonding area and a second conductive bonding area, the first conductive bonding area is arranged on the surface of a first substrate, and the second conductive bonding area is arranged on the side face of the first substrate, that is, a bonding pad connected with a COF is arranged on the side face of an array substrate. On the basis, the conductive efficiency of the bonding pad and the connection stability of the bonding pad and the COF are improved on the premise of being beneficial to narrow-border design and frameless design.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] At present, the narrow bezel and bezel-less design of liquid crystal display (LCD, Liquid Crystal Display) is a development trend. Since the thickness of the bezel is reduced, users will get a wider field of vision when enjoying the display screen , the same size, narrow bezels and bezel-less display devices will make people feel bigger. At the same time, after the frame is removed, the display panel looks like a whole, without traces of splicing, and the appearance is more beautiful. [0003] However, the narrow frame and frameless design makes the conductive area left by the display device for the display panel smaller. Small, resulting in a small contact area between the Bonding pad and COF (Chip On Film, chip-on-film), thereby reducing the conductivity of the Bondin...
