<p>PURPOSE:To enable a gradational display only through digital control and also a homogeneous gradational display even if TFT have slight variance by controlling the time of application of a voltage to pixel electrodes. CONSTITUTION:In each deformed inverter circuit, the gate electrodes of one pair of N and P TFTs at the center part are connected to a signal line Xn and the sources or drains of the N and P TFTs are connected to each other and then connected to the electrode of a pixel Zn+m. The other-side sources or drains of the N and P TFTs are connected to the sources or drains of 2nd N and P TFTs. The other-side sources or drains of the 2nd N and P TFTs are connected to signal lines Yn+1 and Ym respectively. Further, the gate electrodes of the 2nd N and P TFTs are connected to signal lines Yn+1 and Ym respectively.</p> |
