Abstract: A liquid crystal display device includes an array substrate and an opposing substrate that are disposed face to face at a prescribed interval. The array substrate includes a scan line, signal lines, switching devices disposed at intersections between the scan line and the signal lines, pixel electrodes disposed in a matrix manner and driven by the switching devices and auxiliary capacitance lines for retaining applied voltage for the pixel electrodes. The pixel electrodes have side edges superposed on the signal lines or black matrices formed on the opposing substrate to achieve shielding of light, and the side edges have parts superposed on shield electrodes disposed on the auxiliary capacitance lines to make an amount of superposition between the pixel electrodes and the signal lines or the black matrices in a region corresponding to positions where the shield electrodes are disposed smaller than that in other regions.
