Abstract: A thin film transistor and a fabricating method thereof are adaptive for increasing a capacitance of a storage capacitor. In the method, a gate electrode and a lower electrode of a capacitor are formed at the transistor area and the capacitor area of an insulating substrate, respectively. A gate insulating film, an active layer and an ohmic contact layer on the insulating substrate is sequentially formed to cover the gate electrode and the lower electrode.

Then, the ohmic contact layer and the active layer are secondarily patterned in such a manner as to reduce the thickness of the gate insulating film at a portion corresponding to the lower electrode.

Abstract: A liquid crystal display having an increased pixel aperture ratio is disclosed along with a method of making same. An array of a-Si TFTs is deposited on a transparent substrate. Subsequently, an organic insulating layer (e.g. Benzocyclobutene) and a corresponding array of pixel electrodes are deposited over the TFT array so that the pixel electrodes overlap the display address lines thereby increasing the display's pixel aperture ratio. The low dielectric constant ∈ (e.g. about 2.7) and relatively high thickness (e.g. greater than about 1.5 &mgr;m) of the insulating layer reduce the pixel electrode-address line parasitic capacitance CPL in the overlap areas thereby reducing cross-talk (or capacitive coupling) in the display. In sum, an increased pixel aperture ratio is achieved without sacrificing display performance.

Abstract: This invention is related to a thin film transistor (TFT) array and method of making same, for use in an active matrix liquid crystal display (AMLCD) having a high pixel aperture ratio. The TFT array and corresponding display are made by forming the TFTs and corresponding address lines on a substrate, coating the address lines and TFTs with a photo-imageable insulating layer which acts as a negative resist, exposing portions of the insulating layer with UV light which are to remain on the substrate, removing non-exposed areas of the insulating layer so as to form contact vias, and depositing pixel electrodes on the substrate over the insulating layer so that the pixel electrodes contact respective TFT source electrodes through the contact vias. The resulting display has an increased pixel aperture ratio because the pixel electrodes are formed over the insulating layer so as to overlap portions of the array address lines.

The color filters are formed on the active substrate in a manner such that the filters also overlap the address lines and function as an insulating layer between the pixel electrodes and address lines in the areas of overlap. Accordingly, line-pixel capacitances are reduced and the resulting AMLCD is easier to manufacture. The total number of process step in manufacturing is reduced, and plate-to-plate (active to passive plate) alignment is much easier and less important.
