ABSTRACT:
A liquid crystal display is provided, which includes: a first panel including a first signal line, a second signal line intersecting the first signal line, a thin film transistor connected to the first and the second signal lines, and a pixel electrode connected to the thin film transistor and including a first subpixel electrode having a first voltage and a second subpixel electrode capacitively coupled to the first subpixel electrode and having a second voltage; a second panel including a common electrode facing the pixel electrode and supplied with a common voltage; and a vertically aligned liquid crystal layer that is interposed between the pixel electrode and the common electrode, wherein a steepness of light transmittance as function of a voltage applied the first subpixel electrode with respect to the common voltage is lower than about 20.
