  • Patent number: 10304876
    Abstract: This disclosure relates to the field of display technologies, and discloses a method for manufacturing an array substrate, an array substrate, a grayscale mask plate and a display device. The method includes forming a transparent conductive layer and a metal layer sequentially on a base substrate. A photoresist pattern is formed on the base: substrate on which the transparent conductive layer and the metal layer have been formed The transparent conductive layer and the metal layer corresponding to a photoresist-free region are removed. The photoresist in a second photoresist region is removed. The metal layer corresponding to the second photoresist region is removed to expose a pixel electrode. Additionally, the photoresist in a first photoresist region is removed to expose a first electrode, a second electrode and a first data line.

  • Publication number: 20170294465
    Abstract: A film patterning method is provided. The method comprises: performing a dry etching process on a film to be patterned, so as to form a patterned film; removing a suspended particle on the patterned film; and performing another dry etching process on the patterned film after the suspended particle is removed, to form a final pattern of the film. By moving or completely removing the suspended particle on the patterned film and then performing another dry etching process on the patterned film to etch away the etching residue, existence of the etching residue is completely avoided in the final pattern of the film, so that the product yield is improved and the product quality is ensured.

  • Publication number: 20150357373
    Abstract: The present invention provides an array substrate and a manufacturing method thereof and a display device, belonging to the field of display technology and solving the problems that the display quality is reduced and the normal watching is affected due to alignment shifting during alignment in an existing thin film transistor liquid crystal display. The array substrate of the present invention includes a plurality of sub-pixel units, wherein a plurality of light forming units corresponding to the sub-pixel units are arranged on a light-exiting surface of the array substrate, and each of the light forming unit is configured to form light of a color of the sub-pixel units corresponding thereto. When the array substrate of the present invention is applied to the display device, the display quality of the display device may be improved.
