It is an object of the present invention to provide a technique that can expand a dynamic range without allowing transmissivity of a liquid crystal display device of an IPS system to be reduced. A pixel area surrounded and defined by the drain lines and the gate lines. The pixel area includes: a first pixel part having a flat surface-like planar electrode, and a plurality of line-like linear electrodes that are formed in superimposition on the planar electrode via an insulating film and extend in a first direction; a second pixel part having the planar electrode, and a plurality of line-like linear electrodes that are formed in superimposition on the planar electrode via the insulating film and extend in a second direction; a boundary electrode that is formed in an area sandwiched between the first pixel part and the second pixel part, and has a side edge portion inclined in the first direction and aside edge portion inclined in the second direction; and a light-blocking film that is formed in superimposition on the boundary electrode, and has sides formed to extend along the side edge portions of the boundary electrode inclined in the first and second directions.
