Abstract

The present application discloses a display panel and a method for manufacturing the display panel. The display panel includes a first metal layer, an insulating layer, a second metal layer and a binding electrode; the insulating layer is arranged on the first metal layer , the insulating layer has a first hollowed-out portion exposing the first metal layer; the second metal layer is disposed on the insulating layer and extends to the bottom of the first hollowed-out portion to cover the exposed On the first metal layer; the binding electrode is formed on the same side of the first metal layer and the second metal layer. This application increases the contact area between the first metal layer and the second metal layer electrically connected to the binding electrode, reduces the contact impedance of the two, avoids the difference of the picture and the burning of the binding area of ​​the display panel, and improves the performance of the display panel. display effect and yield.

Description

technical field [0001] The present application relates to the technical field of display panels, in particular to a display panel and a method for manufacturing the display panel. Background technique [0002] With the improvement of the liquid crystal display (Liquid Crystal Display, LCD) performance and the COF (Chip On Flex, or, Chip On Film, often called chip on film) binding process, splicing screen technology has been widely used in panel production. The screen market has a wide range of applications, and can be applied to commercial display, outdoor, security monitoring, etc. Most of the existing splicing screens are spliced ​​with multiple sub-display panels, and two adjacent sub-display panels always have areas that cannot be displayed in the splicing area, which is the so-called splicing gap, or splicing seam for short. The seam on the splicing screen affects the display effect. Therefore, narrowing the seam technology has many advantages, such as Ultra Narrow bor...
