Abstract
An array substrate for a liquid crystal display device includes a gate line and a data line crossing each other on a substrate to define a pixel region, an insulating layer between the gate line and the data line, a gate electrode extending from the gate line, and a transistor in the pixel region having an active layer on the insulating layer, ohmic contact layers of a first material that are adjacent to ends of the active layer, buffer layers of a second material, which is different from the first material, on the ohmic contact layers, a source electrode contacting one of the buffer layers and a drain electrode contacting another one of the buffer layers, wherein the active layer is in an island shape over the gate electrode and within a boundary defined by a perimeter of the gate electrode.
