ABSTRACT:
A lateral electric field type LCD device makes it possible to increase the degree of freedom in designing the constituent elements thereof and to improve the aperture ratio easily compared with the related-art LCD structure. The drain bus lines are entirely covered with the at least one first liquid crystal driving electrode (e.g., the common electrode). The gate bus line corresponding to each pixel region is covered with the at least one first liquid crystal driving electrode except for a predetermined non-overlapped area existing in a part that does not overlap with the corresponding TFT. The predetermined non-overlapped area of the gate bus line corresponding to each pixel region is covered with the storage capacitor electrode corresponding to the adjacent pixel region. Preferably, the at least one first liquid crystal driving electrode comprises openings that expose the channel regions of the TFTs, respectively.
