Abstract: An LCD includes: pixel electrodes; a common electrode including a plurality of slits; and a liquid crystal layer interposed between the pixel electrodes and the common electrode. The plurality of slits include a first slit and a second slit that are disposed adjacent to each other in a first direction. The first slit includes a first central portion and a first extension portion extending from the first central portion toward the second slit, and the second slit includes a second central portion and a first extension portion extending from the second central portion toward the first slit. An end of the first extension portion of the first slit and an end of the first extension portion of the second slit are spaced apart from each other; and disposed, in a staggered manner, on opposite sides of an imaginary center line connecting the first central portion and the second central portion.

Abstract: A display device includes: a gate line including a gate line portion; a data line; a transistor including a gate electrode connected to the gate line, a source electrode connected to the data line, and a drain electrode; and a connecting member disposed between the data line and the source electrode, connected to the data line and the source electrode to cross a gate electrode edge of the gate electrode. A connecting portion where a data line edge and a connecting member edge are connected to each other does not overlap the gate line and the gate electrode in a plan view. The data line includes a first data line portion crossing the gate line and a second data line portion connected to the first data line portion and does not overlap the gate line in the plan view.
