  • Patent number: 9865625
    Abstract: The present disclosure provides an array substrate and a method of manufacturing the same, and a display device. TA connecting portion is provided within the overlapping region between the first signal line and the second signal line, is electrically conductive and directly contacts the second signal line. Thus, even when the upper second signal line is broken due to the large step difference within the overlapping region between the first signal line and the second signal line, the connecting portion electrically connected with the broken second signal line can still electrically connect and conduct the broken second signal line, thereby avoiding transmission of signal from being adversely affected by the broken signal line within the overlapping region.
