显示面板及显示装置
摘要：
本申请提供一种显示面板及显示装置，显示面板包括显示区和与所述显示区电连接的邦定区，所述邦定区包括：衬底层组、形成于所述衬底层组上的第一金属层、形成于所述第一金属层上的钝化层、形成于所述钝化层上的第二金属层、形成于第二金属层上的保护层，所述第二金属层借由所述钝化层上的接触孔与所述第一金属层电连接，所述保护层具有多个通孔，所述第二金属层对应于所述多个通孔的部分暴露出来而形成的多个接触电极。本申请中通过对第一有机层进行大面积的刻蚀，使第三连接电极具有更大的裸露面积，从而增大邦定面积，增加ACF粒子的数量，降低邦定电阻，改善邦定良率。
摘要（英）：

The invention provides a display panel and display device. The display panel includes a display area and a bonding area connected to the display area; the bonding area includes a substrate layer set,first metal layers formed on the substrate layer set, passivation layers formed on the first metal layers, second metal layers formed on the passivation layers, and protective layers formed on the second metal layers; the second metal layers are electrically connected to the first metal layers through the contact holes in the passivation layers; the protective layers have multiple through holes; and the parts of the second metal layers corresponding to the through holes are exposed to form multiple contact electrodes. Through the large area etching on first organic layers, third connection electrodes can have larger bare areas, and therefore, bonding areas can be enlarged, the number of ACF particles can be increased, bonding resistance can be reduced, and the yield rate of bonding can beimproved.
