The invention prevents the display unevenness of a high-resolution liquid crystal display device that results from the presence of regions where an alignment film is not applied. The invention provides a liquid crystal display device including: a TFT substrate having scan lines, video signal lines, and pixels formed by the intersecting scan lines and video signal lines; a counter substrate; and a liquid crystal layer placed between the TFT substrate and the counter substrate. Each of the pixels includes a TFT, a pixel electrode, a common electrode, and a through-hole and an opening that are used to connect the TFT and the pixel electrode. Connective ITO is formed in and around the through-hole at the same time as the common electrode is formed. A step d is formed at an edge portion of the connective ITO and covered with an alignment film.
