1. An array substrate of thin film transistor liquid crystal display (TFT-LCD) comprising gate lines and data lines, in which pixel electrodes and thin film transistors are formed within the pixel region defined by the gate lines and the data lines, wherein a barrier layer pattern is disposed between a semiconductor layer pattern and an ohmic contact layer pattern in the thin film transistor for preventing the semiconductor layer pattern from being etched, wherein an area of the barrier layer pattern is smaller than an area of the semiconductor layer pattern so that the ohmic contact layer pattern is in contact with the semiconductor layer pattern.
