Abstract
An active matrix type liquid crystal display device comprises a liquid crystal layer interposed between first and second substrates, plural scanning signal lines and plural video signal lines arranged in a matrix form on the first substrate and a plural pixels formed in regions surrounded by adjacent scanning signal lines and adjacent video signal lines. Each pixel in the display region has at least an active device, a pixel electrode, and a counter electrode to drive liquid crystal molecules in the liquid crystal layer by applying a voltage difference between the counter electrode and the pixel electrode which are provided are on the same substrate. The driving of the liquid crystal molecules by applying the voltage difference includes rotation of the liquid crystal molecules in a plane substantially parallel to the substrate with plural directions so as to reduce viewing angle dependency of color tone change.
