Abstract: A display device includes a plurality of pixels, at least one of which includes a pixel electrode, a switch, a storage electrode, and a storage electrode, and a storage electrode connecting portion. The pixel electrode is in a pixel area corresponding to a first gate line, a second gate line, a first data line, and a second data line. The switch is connected to the first gate line, the first data line, and the pixel electrode. The storage electrode is adjacent to the pixel electrode. The storage electrode connecting portion is connected to the storage electrode and overlaps at least one of the first gate line or the second gate line. At least a portion of the storage electrode connecting portion is substantially parallel to the overlapped one of the first gate line or the second gate line.
