A Liquid Crystal Display (LCD) device and a method of manufacturing the same are provided. The liquid crystal molecules are inclined and rearranged in a radial shape by patterning upper and lower electrodes across and apart from each other on dummy pixels disposed on a black matrix formed in a non-display area of an LCD device and applying an electric field to a liquid crystal layer via the upper and lower electrodes. Thus, ion impurities in the non-display area can be prevented from dispersing to a display area, thereby improving edge part stains of the LCD device. The LCD device includes a first substrate including first pixel electrodes of the dummy pixels; a second substrate facing the first substrate and including first common electrodes formed across and apart from the first pixel electrodes; and a liquid crystal layer disposed between the first substrate and the second substrate, and having liquid crystal molecules rearranged by an electric field applied via the first pixel electrodes and the first common electrodes.
