Abstract: An array substrate for liquid crystal displays and a liquid crystal display including the same. The array substrate includes a display unit including a thin film transistor, a pad unit disposed at one side of the display unit, and a dummy unit disposed at the other side of the display unit. Here, a blocking unit for blocking a liquid crystal alignment layer from spreading is disposed on each of the pad and dummy units. A first blocking unit for blocking the liquid crystal alignment layer from spreading to the pad unit is disposed on the pad unit. A second blocking unit for blocking the liquid crystal alignment layer from spreading to the dummy unit is disposed on the dummy unit. The liquid crystal alignment layer can be blocked from spreading to the pad unit or to a pad unit of an adjacent array substrate in manufacture of a liquid crystal display, thereby enabling omission of a separate process for removing the liquid crystal alignment layer on the pad unit.
