Abstract:
An active matrix type liquid crystal display device comprising:a liquid crystal layer interposed between first and second substrates; plural scanning signal lines and plural video signal lines being arranged in a matrix form on the first substrate; plural pixels formed in regions surrounded by adjacent scanning signal lines and adjacent video signal lines; each pixel in a display region having 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 said counter electrode and said pixel electrode; wherein said counter electrode and said pixel electrode are provided on the same substrate; wherein the driving of the liquid crystal molecules by applying the voltage difference between said pixel electrode and said counter electrode includes enabling rotation of the liquid crystal molecules in a plane which is substantially parallel to the said substrate; and wherein the rotation of the liquid crystal molecules is effected in plural directions simultaneously to reduce viewing angle dependency of a color tone change.
