Claim:
A liquid crystal display device comprising: a first substrate; a second substrate arranged opposite to the first substrate; a liquid crystal layer sealed between the first substrate and the second substrate, wherein the first substrate comprises: a plurality of gate wires; a plurality of source wires that intersect the plurality of gate wires; a slit electrode that has a plurality of slit-like apertures so as to form a plurality of line-like patterns substantially in a same direction as either the source wires or the gate wires, with a main line-like pattern; and a plate-shaped electrode that has an overlap area with the slit electrode as viewed in plan view, through an insulating layer, the plate-shaped electrode being on a lower layer than the slit electrode, the second substrate comprises: a plurality of color filter films; and a light shielding film that partitions color filter films and extends substantially in a same direction as the line-like patterns of the slit electrode, and that has an overlap area with either the source wires or the gate wires as viewed in plan view, and that is arranged so that the plurality of color filter films are partitioned to prevent color mixture when displayed in a single color, either the plate-shaped electrode or the slit electrode is defined as a pixel electrode arranged so as to be connected to the plurality of source wires through a switching element, and the other electrode is defined as a common electrode, and a non-opposed area to the light shielding film is formed at each end of a main portion of the slit electrode in the width direction so that 6 a transmittance may not be reduced due to the light shielding film in the areas where the light shielding film and the slit electrode are arranged in an overlapped manner, as viewed in plan view, wherein the light shielding film extends outward farther than one of the source wire and the gate wire, and the light shielding film has a width such that there is no color mixture in a view angle range between plus and minus 45 degrees when a single color is displayed, wherein the slit electrode and the plate-shaped electrode are composed of transparent electrodes, wherein the slit electrode comprises an S-slit electrode disposed above one of the source wire as viewed in plan view, wherein the plate-shaped electrode is disposed below the S-slit electrode layer and opposite to an end in the width direction of the S-slit electrode as viewed in plan view, and wherein in the area where the width-direction end of the S-slit electrode and the plate-shaped electrode are arranged to be opposed to each other, a part that is not opposed to the light shielding film is formed in the S-slit electrode so that the light shielding film is not opposed above an area in which a highest-transmittance part is formed.
