The invention provides a thin film transistor substrate and a display device including the same. The thin film transistor substrate includes: a substrate; a gate line, a gate insulating layer and an active layer sequentially formed on the substrate; a source and a drain simultaneously formed on the active layer to from a thin film transistor; an insulation layer formed on the thin film transistor, wherein a via is formed in the insulation layer, and the via is formed on a portion of the drain and a portion of the active layer to expose the portion of the drain and the active layer; and a pixel electrode formed in the via and on the insulation layer, wherein the pixel electrode is electrically connected to the drain through the via. |
