Abstract:
A liquid crystal display apparatus of IPS system comprising:a pair of substrates opposing each other: a liquid crystal sandwiched between said pair of substrates: a plurality of gate lines and a plurality of signal lines which cross each other and are provided on one of said pair of substrates: a plurality of thin film transistors provided to intersections of said gate line and said signal line; and pixel electrodes and common electrodes, both of which are provided at each pixel surrounded by said gate line and said signal line, each of which has bent points more than one and is alternately formed in parallel with each other, both of said pixel electrodes and said common electrodes having: bent sections; and projected sections projecting toward concave section of said bent section of an opposite electrode side from convex side top section of said bent section, and said common electrode around said pixel arranged close to said signal line being formed in such a way that outer edge of the side of said signal line is formed in the shape of a straight line along said signal line, wherein said IPS system liquid crystal display apparatus allows liquid crystal molecule to be rotated within a surface in approximately parallel with said substrate by applying a voltage to said pixel electrode and said common electrode therebetween.
