Liquid crystal display apparatus

A liquid crystal display apparatus of IPS system comprising:

• a pair of substrates opposing to each other;
• a liquid crystal sandwiched between said pair of opposite 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;
• pixel electrodes and common electrodes, both of which are provided at each pixel surrounded by said gate line and said signal line, and each of which is alternately formed in parallel with each other,
• in which said IPS system liquid 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,
• said liquid crystal molecule is initially oriented obliquely to a direction at right angles to said gate line, and
• said TFT is stationed so that a gate length direction of said TFT is in approximately parallel with said initial orientation direction or is at approximately right angles to said orientation direction.
