Abstract
The present invention provides a fringe field switching (FFS) mode liquid crystal display device that makes it possible to improve transmittance when a voltage is applied. The fringe field switching mode liquid crystal display device of the present invention includes: a first substrate; a second substrate arranged facing the first substrate; and a liquid crystal layer sandwiched between the first substrate and the second substrate, wherein the first substrate includes, in order, a plurality of pixel electrodes, an insulating film covering the plurality of pixel electrodes, and a common electrode that is layered on top of the plurality of pixel electrodes and has a plurality of parallel slits formed therein, wherein steps that protrude towards a liquid crystal layer side are formed in the first substrate in at least sides of regions between the plurality of pixel electrodes that are parallel to a lengthwise direction of the plurality of parallel slits, and wherein the common electrode covers at least side faces of the steps.
