Disclosed is an active matrix liquid crystal display device including substrates and a liquid crystal layer. The substrate includes: scan signal wiring lines; common signal wiring lines; video signal wiring lines intersecting these wiring lines; and pixels surrounded with the scan signal wiring lines and the video signal wiring lines. Each of pixels includes: a thin film transistor; source electrodes in a layer with the video signal wiring lines; pixel electrodes connected to the source electrodes; and common electrodes connected to the common signal wiring lines. The source electrodes include first parts overlapping the scan signal wiring lines and second parts connecting with the pixel electrodes, which are positioned around central parts between the video signal wiring lines. Molecular axes in the liquid crystal layer rotate under an electric field applied between the pixel electrodes and the common electrodes.

Method of manufacturing an LCD device

A liquid crystal display device includes an active matrix substrate and a counter substrate opposing each other with a gap therebetween defined by a plurality of columnar spacers. The active matrix substrate has a plurality of spacer holes each receiving therein a corresponding one of the columnar spacers, and a plurality of dummy spacer holes aligned with the spacer holes and each receiving therein no columnar spacer.

An in-plane switching mode LCD device includes a shield common electrode having a protrusion protruding from side edges of a drain line, and a pair of light shield films sandwiching therebetween the drain line and having an overlapping portion overlapping the protrusion. The shield common electrode shields the electric field from the drain line, and the light shield films improve the contrast ratio of the LCD device.
