  • Liquid crystal display apparatus having a series combination of the storage capacitors
    Patent number: 5151806
    Abstract: An active matrix-type liquid crystal display apparatus, in which a pixel electrode and a common electrode line are not overlapped but coupled capacitively by a floating electrode, so that the pixel electrode and common electrode do not short-circuit, and a storage capacitance is formed by the series connection of a plurality of capacitors. An active matrix-type liquid crystal display apparatus, in which a pixel electrode and a gate electrode line at the succeeding or preceeding row are not overlapped but coupled capacitively by a floating electrode, so that the pixel electrode and gate electrode do not short-circuit, and a storage capacitance is formed by the series connection of a plurality of capacitors.
