  • Publication number: 20140159073
    Abstract: The present invention provides an array substrate and a method for manufacturing the same, and a display device. Wherein, after forming a pattern corresponding to a source/drain electrode layer, a transparent conducting layer is formed, and then a passivation layer is formed on the transparent conducting layer.
