  • Patent number: 9768275
    Abstract: An array substrate for a liquid crystal display (LCD) device includes a common line and gate lines. The array substrate includes a first, second, and third passivation layer and thin film transistors (TFTs). The second passivation layer includes first and second holes respectively corresponding to a drain electrode and the common line. A common electrode on the second passivation layer includes a first opening corresponding to the TFTs and a second opening in the second hole. A drain contact hole through the third and first passivation layers exposes the drain electrode. A first common contact hole through the third passivation layer exposes the common electrode in the second hole. A second common contact hole through the third and first passivation layers exposes the common line, and a pixel electrode includes a third opening and a connection pattern connecting the common electrode to the common line on the third passivation layer.
