LCD med buslinier overlappet af pixelelektroder og fotofølsomt isolerende lag derimellem

摘要

This invention is related to an active matrix liquid crystal display (AMLCD) having a high pixel aperture ratio. The 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. Both the manufacturability and capacitive cross-talk of the TFT-based device are improved due to the use of an insulating layer (33) between the pixel electrodes (3) and the address lines (7). According to certain other embodiments, the insulating layer may be BCB (either photo-imageable or not) and/or have a dielectric constant less than about 3.0.
