LIQUID CRYSTAL DISPLAY DEVICE AND SEMICONDUCTOR DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18231950 titled 'LIQUID CRYSTAL DISPLAY DEVICE AND SEMICONDUCTOR DEVICE

Simplified Explanation

The patent application describes a method for controlling the gradient of an electric field applied to liquid crystals by increasing the interval between electrodes that drive the liquid crystals.

  • The invention aims to optimize the electric field applied between the electrodes in order to improve the performance of liquid crystal displays.
  • The device includes a first electrode, an insulating film, and a thin film transistor formed over a substrate.
  • The thin film transistor includes a semiconductor film with a source, channel region, and drain.
  • A second electrode, with first opening patterns, is located over the semiconductor film and the first electrode.
  • Liquid crystals are provided over the second electrode.
  • By adjusting the interval between the electrodes, the gradient of the electric field can be controlled, leading to improved display quality.


Original Abstract Submitted

By increasing an interval between electrodes which drives liquid crystals, a gradient of an electric field applied between the electrodes can be controlled and an optimal electric field can be applied between the electrodes. The invention includes a first electrode formed over a substrate, an insulating film formed over the substrate and the first electrode, a thin film transistor including a semiconductor film in which a source, a channel region, and a drain are formed over the insulating film, a second electrode located over the semiconductor film and the first electrode and including first opening patterns, and liquid crystals provided over the second electrode.
