Abstract

The present application provides a display panel and a display device. The display panel includes a display area and a bonding area electrically connected to the display area. The bonding area includes: a substrate layer group, a first layer formed on the substrate layer group A metal layer, a passivation layer formed on the first metal layer, a second metal layer formed on the passivation layer, a protective layer formed on the second metal layer, the second metal layer is The contact hole on the passivation layer is electrically connected to the first metal layer, the protective layer has a plurality of through holes, and the second metal layer is formed by exposing parts corresponding to the plurality of through holes. multiple contact electrodes. In this application, by etching the first organic layer in a large area, the third connecting electrode has a larger exposed area, thereby increasing the bonding area, increasing the number of ACF particles, reducing the bonding resistance, and improving the bonding quality. Rate.

Description

technical field [0001] The present application relates to the display field, in particular to a display panel and a display device. Background technique [0002] Thin film transistors are widely used as pixel switching elements or driving circuit elements in various display devices, such as liquid crystal displays, organic light emitting diode displays, electronic paper displays, and the like. A pixel array of a display device is usually defined by multiple rows of gate lines and multiple columns of data lines interlaced with them. In the sub-pixel unit, the thin film transistor is used as a switching element, and under the control of the gate, an external data signal can be written into the pixel electrode in the sub-pixel unit through the thin film transistor to implement charging and discharging. [0003] Usually, the driving signal is provided by an integrated driving circuit (IC chip) bonded on the array substrate. Therefore, the bonding yield has a great influence on...
