    摘要： In an array substrate two pixel electrodes (P,PB) are arranged in a pixel unit and each of the pixel electrodes is respectively controlled by a corresponding TFT (T1,T2), the rotation direction of the liquid crystal molecules may be controlled by the voltage difference between the two pixel electrodes (P,PB), while the voltage on the pixel electrodes of other pixel units in the array substrate is not affected, to avoid a greenish phenomenon. Furthermore, since the two TFTs (T1,T2) for controlling the two pixel electrodes (P,PB)respectively have a same parasitic capacitor, when the pixel unit is turned off, the voltage difference between the two pixel electrodes is kept unchanged and image flicker can be avoided.

    摘要： A display apparatus, that includes current driving type luminescent elements, has a driving system that takes the conduction types of TFTs to control the emission of the luminescent elements into consideration. In order to reduce driving voltage and improve display quality simultaneously, the arrangement is provided such that if the second TFT (30) which performs the "on-off" function of the current for the luminescent element (40) is of an N channel type, the potential of the common power supply line ("com") is lowered below the potential of the opposite electrode ("op") of the luminescent element (40) to obtain a higher gate voltage ("Vgcur"). In this case, if the first TFT (20) connected to the gate of the second TFT (30) is of a P channel type, when using the potential of the potential-holding electrode ("st") at the "on" state as a reference, potentials of the scanning signal ("Sgate") at the lower potential and the common power supply line ("com") are rendered of the same polarities with respect to this potential of the potential-holding electrode ("st"). Therefore, the potential of the image signal ("data") to turn "on" can be shifted within the range of the driving voltage in the display apparatus (1) in the direction to reduce resistances at the "on" states of the first TFT (20) and the second TFT (30) to reduce driving voltage and improve display quality.
