A display device is capable of improving image quality, the display device including: a first substrate and a second substrate facing each other; a common electrode between the first substrate and the second substrate, the common electrode including a first area and a second area; a first pixel group including a plurality of first pixel electrodes located at a display area of the first substrate and overlapping the first area of the common electrode; a second pixel group including a plurality of second pixel electrodes located at the display area of the first substrate and overlapping the second area of the common electrode; a first auxiliary line physically connected to the first area of the common electrode; a second auxiliary line physically connected to the second area of the common electrode; a first connection portion located at a non-display area of the first substrate and electrically connected to the first auxiliary line; and a second connection portion located at the non-display area of the first substrate and electrically connected to the second auxiliary line. The first connection portion and the second connection portion do not physically contact each other.
