Array substrate for liquid crystal display and method for manufacturing the same

摘要

An array substrate for a liquid crystal display includes a substrate and first and second subpixels which are positioned on the substrate and are defined by a crossing structure of one gate line, a first data line, a second data line, a first common line, and a second common line. The first subpixel includes a first semiconductor layer, a first source electrode, a first drain electrode, and a first pixel electrode connected to the first drain electrode. The second subpixel includes a second semiconductor layer, a second source electrode, a second drain electrode, and a second pixel electrode connected to the second drain electrode. The first and second subpixels share the one gate line with each other, and the first drain electrode and the second drain electrode are exposed through one contact hole.
