1. An active matrix liquid crystal display panel comprising:

  • a first transparent insulating substrate;

    a second transparent insulating substrate opposing said first transparent insulating substrate;

    a liquid crystal layer provided between said first and said second transparent insulating substrates;

    a scanning line and a signal line provided on said first transparent insulating substrate in such a manner as to partition a main surface of said first transparent insulating substrate into a grating;

    a thin film transistor provided in said grating;

    a pixel electrode connected to said thin film transistor said pixel electrode having a comb shape with teeth;

    an opposing electrode opposing said pixel electrode, said opposing electrode having a comb shape with teeth extending into the spaces between the teeth of said pixel electrode to form pixels such that a display is controlled by electric fields generated substantially in parallel to said liquid crystal layer by applying voltages between said pixel and said opposing electrodes;

    wherein a bus line for supplying the potentials to said opposing electrode is formed in a layer different from the layers in which said scanning lines and said signal lines are formed.
