A liquid crystal display device having a plurality of pixel regions formed on a liquid-crystal-side surface of one substrate of a pair of substrates which are arranged to face each other in an opposed manner by way of a liquid crystal, and surrounded by a plurality of gate signal lines which are arranged in parallel and a plurality of drain signal lines which cross the gate signal lines and are arranged in parallel, each pixel region comprising a switching element which is operated in response to a scanning signal from one of the gate signal lines, a pixel electrode to which a video signal is supplied from one of the drain signal lines through the switching element, and a counter electrode to which a signal which provides a reference with respect to the video signal is supplied through a counter voltage signal line. The counter voltage signal line comprises one of an Al layer and an Al alloy layer which is formed below a plurality of insulation layers, and the counter electrode is formed over the plurality of insulation layers, covers the plurality of drain signal lines, and has a connection portion thereof connected to the counter voltage signal line via through holes formed in the plurality of insulation layers.
