Abstract

A liquid crystal display and a method for fabricating the same are disclosed. The method for fabricating a liquid crystal display, which includes preparing an insulating substrate defining a pixel portion divided into a thin film transistor region and a storage region, sequentially forming a polycrystalline silicon film and a storage electrode film on an entire surface of the substrate, selectively patterning the storage electrode film and the polycrystalline silicon film to form a pixel pattern that covers the pixel portion, and selectively removing the storage electrode film of the thin film transistor region from the pixel pattern to form a storage electrode in the storage region and at the same time form an active layer in the thin film transistor region, the active layer being formed of a polycrystalline silicon film exposed by the storage electrode. Since the active layer and the storage electrode are formed by diffraction exposure using a single mask, the number of masks used in fabrication of a thin film transistor can be reduced to reduce the fabricating process steps and the fabricating cost.
