    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： A liquid crystal display device, and a fabricating method thereof, that is capable of providing uniform liquid cell gaps. A main seal defines a liquid crystal injection area. A first step coverage-compensating layer is provided between a substrate on which the main seal has been coated and the main seal. A plurality of dummy seals is arranged external to the main seal. A second step coverage-compensating layer having the same thickness as the first step coverage-compensating layer is provided between the substrate on which the dummy seals are arranged and the dummy seals. Accordingly, a main seal and dummy seals having the same thickness produce uniform liquid crystal cell gaps. The liquid crystal display device is beneficially made by a fabrication process employing four or five masks.
