  • Publication number: 20060038957
    Abstract: A method of manufacturing an array substrate for a liquid crystal display device which includes forming a gate electrode, a gate line, and a gate pad on a substrate by sequentially depositing a metal layer and a transparent conductive layer and patterning, forming a gate insulating layer on the gate electrode, the gate line, and the gate pad, forming an active layer on the gate insulating layer over the gate electrode, forming an ohmic contact layer on the active layer, forming source and drain electrodes, a data line and a data pad on the ohmic contact layer, forming a pixel electrode, forming a data pad terminal covering the data pad, forming a passivation layer on the pixel electrode and the data pad terminal, exposing the gate pad by etching the passivation layer and the gate insulating layer, and exposing the data pad terminal by etching the passivation layer.

  • Publication number: 20050275340
    Abstract: A method of fabricating an electrode for an organic electroluminescent device includes forming a transparent conductive layer on a substrate, doping the transparent conductive layer with impurities, and annealing the doped transparent conductive layer.

  • Patent number: 6972820
    Abstract: A method of manufacturing an array substrate for a liquid crystal display device which uses KAPTON tapes on the gate pad or data pad to expose the gate pad and the data pad after subsequent processing steps. The method can also adopt a double structure of a metal layer and a transparent conductive layer for a gate electrode and a gate pad. The method can also use a metal mask. A diffraction exposure technique can also be adopted to decrease manufacturing time and cost.
