Abstract: A liquid crystal display includes a first substrate, a first subpixel electrode, a connecting electrode, and a second subpixel electrode. The first subpixel electrode is on the first substrate and includes a first stem extending in a first direction and a plurality of branches extending from the first stem. The connecting electrode is electrically connected to the first subpixel electrode. The second subpixel electrode is on the same layer as the first subpixel electrode and includes a plurality of separation electrodes that do not overlap the connecting electrode. At least one of the separation electrodes is between a first sub branch and a second sub branch, which neighbor each other from among the branches. The second subpixel electrode is a floating electrode.
