Abstract
The object of the present invention is to prevent a light leakage from a boundary portion between the areas where the voltage to be applied to the liquid crystal varies, and reducing a light leakage on a contact hole provided for electrically connecting the first pixel electrode and the second pixel electrode in the case where the areas where the voltage to be applied to the liquid crystal varies are composed of two-layered pixel electrodes, namely, a first pixel electrode and a second pixel electrode. A liquid crystal display device of the invention includes a plurality of pixels provided on an insulating substrate, a scanning line provided on the insulating substrate which scans the pixels, liquid crystal which is interposed between the insulating substrate and a counter substrate countered to the insulating substrate, and areas where a voltage to be applied to the liquid crystal varies in one pixel, and is characterized in that a light shielding film for preventing a light leakage due to alignment disorder of the liquid crystal is provided to a boundary portion of the areas where the voltage to be applied to liquid crystal varies.
