Patent ID: 7057596

Claim:
A display device comprising: a plurality of scanning lines and a plurality of signal lines which are arranged to cross said plurality of scanning lines and forming each pixel corresponding to a region surrounded by said plurality of scanning lines and said plurality of signal lines; each said pixel including a pixel electrode, a switching element for selecting said pixel electrode, and a storage circuit formed between said pixel electrode and said switching element for storing data to be written in said pixel electrode; a pair of alternating voltage power source lines, for applying alternating voltages varying in polarities opposite to each other connected to said storage circuit; wherein said storage circuit has a first pair of transistors including an NMOS transistor and a PMOS transistor connected in series across said pair of alternating voltage power source lines, and a second pair of transistors, including an NMOS transistor and a PMOS transistor, which are connected in series across the pair of alternating voltage power source lines and in parallel with respect to the first pair of transistors, wherein a common connection point of control electrodes of said first pair of transistors is connected to a series connection intermediate point of said second pair of transistors, and a common connection point of control electrodes of the second pair of transistors is connected to a series connection intermediate point of the first pair of transistors, wherein an output point of said switching element is connected to a connection point of said first pair of transistors, wherein said series connection intermediate point of said second pair of transistors is connected to said pixel electrode, and wherein a capacitor is connected between said common connection point of said control electrodes of said second pair of transistors and said series connection intermediate point.
