The array substrate and the manufacturing method, a display device

The present invention provides a method for manufacturing an array substrate and a display device, the array substrate comprising: forming an electrode pattern and a lining on the backing plate; said electrode pattern comprises a plurality of strip electrodes; said backing plate the upper surface of the strip having a plurality of protrusions, at least a portion of said plurality of strip electrode strip electrodes formed on corresponding strip-like protrusions; extending direction of each of the strip electrodes and each strip extending protrusion direction having an angle, with the angle is adapted to extending direction of each strip-like protrusions rubbing direction of the film. The present invention provides an array substrate, the rubbing is performed when the film can be made along the bar-shaped protrusions extending direction, so as to avoid the influence of the level difference of the angle strip protrusions friction obtained, to avoid the resulting light leakage.
