摘要： A liquid crystal display device and a fabricating method thereof wherein four masks are used so as to reduce a process. In the device, a gate electrode is formed on a transparent substrate. A gate insulating film is formed on the transparent substrate to cover the gate electrode. An active layer is provided at a portion corresponding to the gate electrode on the gate insulating film. Source and drain electrodes are intervened by an ohmic contact layer on the active layer. A contact portion is connected to and extended from a portion of the drain electrode opposed to the source electrode and has an exposed side surface. A passivation layer is formed on the active layer in such a manner to cover the source and drain electrodes, but to expose the side surface of the contact portion. A pixel electrode is formed on the gate insulating film in such a manner to contact the exposed side surface of the contact portion. Accordingly, the contact portion connected to and extended from a portion of the drain electrode opposed to the source electrode or a plurality of comb-shaped contact portions having the exposed side surfaces are formed in such a manner to overlap with the black matrix of the upper plate provided with color filters. Accordingly, the pixel electrode contacts the side surface of the contact portion overlapping with a black matrix of an upper plate to be electrically connected to the drain electrode, so that an aperture ration can be improved.

摘要： The present invention relates to a method for keeping contact resistance of a pad low. The present invention also discloses a structure of the pad and a method for manufacturing the same, for use in circuit boards and LCD displays. The pad terminal comprises a first metal layer and a second metal layer covering the first metal layer. The second metal layer is removed before the pad terminal is deposited. Thus, the surface of the pad is clean and contact resistance is kept low, because there are no contaminants on the pad. Furthermore, the present invention discloses a pad having a raised part and a depressed part, enlarging the contact area of the pad. Therefore, contact resistance is reduced, and adhesion between the pad and the pad terminal is enhanced.
