US Patent 8654069 Display device

In a display device, pixel electrodes I, II and III corresponding to color filters R, G and B are coupled to TFTs which are turned on in accordance with signals on gate lines G, and the drain (source) of the TFT coupled to the pixel electrode II is connected with the source (drain) of the TFT coupled to the pixel electrode III. A signal voltage is written in the pixel electrode I when the gate line G1a is in the “on” state, a signal voltage is written in the pixel electrode II when the gate line G1b is in the “on” state, and a signal voltage is written in the pixel electrode III when the gate lines G1a and G1b are both in the “on” state. Signal voltages are written in the pixel electrodes III, I and II in this order mentioned.
