  • Patent number: 7199808
    Abstract: The present invention aims at providing a liquid crystal display which can reproduce images in a uniform manner. In a liquid crystal display which adopts an area ratio gray scale and includes pixels each having a plurality of sub-pixels, the sub-pixel includes a sub-pixel electrode and two TFTs, and is connected to a common line to which a predetermined voltage is applied. To the source electrode and drain electrode of one TFT, the drain electrode of the other TFT and the sub-pixel electrode are connected, respectively. To the source electrode of the other TFT, either a scanning signal line or a data signal line is connected. Meanwhile, to the gate electrode of said one TFT, either the scanning signal line or the data signal line which is not connected to the gate electrode of the other TFT is connected.
