Abstract
In a liquid crystal display (LCD device), according to the present invention, multiple common electrodes (5) are formed above the TFTs substrate, so as to overlap the respective data bus lines (2), which belong to the same column of the TFTs matrix. Whereas multiple common bus lines (3) are formed, so as to overlap both the respective gate bus lines (7, 1), which belong to the same line of the matrix, and the TFTs (6). With this arrangement, unnecessary electric fields coming into the liquid crystal layer (18) can be shut out. The common bus lines (3) and the common electrodes are both formed on or in the inter-layer insulating film (12), towards the side of the said liquid crystal layer (18). Whereas, the data bus lines (2), the said gate bus lines (7, 1), and pixel electrodes (4) are all formed far away from the liquid crystal layer, across the inter-layer insulating film (12).
