ABSTRACT:
A liquid crystal display includes: a first substrate; a gate line disposed on the first substrate; a data line intersecting the gate line; a thin film transistor connected to the gate line and the data line; a coupling electrode connected to the thin film transistor; a first sub-pixel electrode connected to the thin film transistor; a second sub-pixel electrode capacitively coupled to the coupling electrode; a second substrate facing the first substrate; a common electrode disposed on the second substrate; and a polarizer disposed on the first substrate or the second substrate and having a polarization axis. The coupling electrode is elongated substantially parallel to the polarization axis and has a first edge substantially parallel to or substantially perpendicular to the polarization axis.
