Abstract
A method of fabricating an array substrate structure for a liquid crystal display device includes defining a display area and a non-display area on a substrate, the display area having a pixel TFT portion and a pixel electrode area, and the non-display area having an n-type driving TFT portion and a p-type driving TFT portion; forming a first gate electrode in the display area, a second and a third gate electrodes and a first capacitor electrode in the non-display area; an amorphous silicon layer on the substrate; crystallizing the amorphous silicon layer to a polycrystalline silicon layer and doping specific portions of the polycrystalline silicon layer with plurality of impurity concentrations; and forming a first semiconductor layer in the display area, a second and a third semiconductor layers and a second capacitor electrode in the non-display area.
