Abstract:
A liquid crystal display device comprising: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; wherein the counter electrode is formed below a plurality of insulation layers; and wherein the counter voltage signal line is formed of a non-light-transmitting conductor, is formed over the plurality of insulation layers, and covers the plurality of drain signal lines, and has portions thereof electrically connected to the counter electrode via at least one through hole formed in the plurality of insulation layers.
