Abstract
An in-plane switching (IPS) liquid crystal display device (100) includes pixel units each having a storage capacitor. The storage capacitor is formed by a common electrode (112), a drain electrode (103), and a counter electrode (110). The common electrode is electrically coupled with the counter electrode. The counter electrode substantially covers the drain electrode, for shielding unexpected coupling effects on the drain electrode due to data signals on a data line (101) driving other pixels of the liquid crystal display device.
