US Patent 11049922 Flexible array substrate and display panel

A flexible array substrate and a display panel are provided. The flexible array substrate comprises a flexible substrate, a buffer layer, a plurality of signal lines, and pixel electrodes. The buffer layer is disposed on the flexible substrate. The plurality of signal lines is disposed on the buffer layer. A shape of the signal lines in a cross-sectional direction of the flexible array substrate is a curved shape with undulating portions or a polyline shape with undulating portions. In the disclosure, the signal line that has a curved shape with undulating portions or a polyline shape with undulating portions is disposed on the buffer layer, so that the signal line is able to cope with bending stress when bending.
