Array substrate, manufacturing method thereof and liquid crystal panel

The invention discloses an array substrate, a manufacturing method thereof and a liquid crystal panel, and belongs to the technical field of display. The array substrate comprises a substrate, and a pixel electrode, an auxiliary signal line, a signal transfer line and a first transfer electrode which are located on one side of the substrate. The auxiliary signal line can comprise a first sub-signal line and a second sub-signal line which are arranged in different layers, and the first sub-signal line and the second sub-signal line can be electrically connected through a first switching electrode. Thus, it can be ensured that the conductive parts connected together in the metal film layer comprising the first sub-signal line do not comprise the second sub-signal line, and the orthographic projection area of the conductive parts connected together in the metal film layer on the substrate is small. Therefore, static electricity generated in the preparation process of the array substrate is not easy to store in the conductive parts connected together in the metal film layers, so that the probability that the array substrate generates an ESD phenomenon is low, and the yield of the array substrate can be effectively improved.
