Active-matrix liquid crystal display

摘要

On a TFT substrate, a TFT using a low-temperature poly silicon thin film as an active layer is formed and a plurality of pixel electrodes are formed over the TFT and its electrode wiring, with an interlayer insulating layer between. In a common electrode formed on an opposite substrate opposite the TFT substrate with a liquid crystal layer between, an alignment controlling window for the liquid crystal is formed at a predetermined position opposite each of the pixel electrodes. A wide viewing angle is achieved by dividing an alignment area of liquid crystal molecules in one pixel area. The liquid crystal layer is vertically aligned and can be operated at a low driving voltage obtained by a poly silicon TFT by including fluorine liquid crystal molecules having negative dielectric anisotropy and fluorine side chains in the liquid crystal.
