Abstract: A liquid-crystal display device includes a substrate, a thin-film transistor (“TFT”) disposed on the substrate, an insulation film disposed on the TFT, a pixel electrode disposed on the insulation film, an expanded electrode disposed in a same layer as the pixel electrode, a connection electrode which is disposed in the same layer as the pixel electrode and connects the pixel electrode with the expanded electrode, and a shield electrode disposed in the same layer as the pixel electrode and separated from the pixel electrode, the connection electrode and the expanded electrode, where the expanded electrode is electrically connected to the TFT via a contact hole defined in the insulation film, and where the shield electrode includes a first shield portion disposed between the pixel electrode and the contact hole in a plan view, and a second shield portion other than the first shield portion.
