    摘要： For the purpose of providing a display apparatus capable of improving display quality by expanding the light-emission area of pixels by improving the layout of pixels and common power-feed lines formed on a substrate, pixels (7A, 7B) including a light-emission element (40), such as an electroluminescence element or an LED element, are arranged on both sides of common power-feed lines (com) so that the number of common power-feed lines (com) is reduced. Further, the polarity of a driving current flowing between the pixels (7A, 7B) and the light-emission element (40) is inverted so that the amount of current flowing through the common power-supply lines “com” is reduced.

    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 which performs the “on-off” function of the current for the luminescent element 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 to obtain a higher gate voltage (“Vgcur”). In this case, if the first TFT connected to the gate of the second TFT 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 and the second TFT to reduce driving voltage and improve display quality.

    摘要： A driving circuit of an electro-optical device such as a liquid crystal device is compatible with digital image signals and implements a DA converting function and a &ggr; correcting function by a relatively simple and small-scale circuit configuration. The driving circuit of the liquid crystal device is provided with a DAC 3 for issuing a voltage signal VC corresponding to N bits of digital image data DA that indicate a gray scale value to a signal line of the liquid crystal device. Depending on whether the value of a most significant bit is “0” or “1,” the DAC 3 brings the output driving voltage characteristic close to the optical characteristics of the liquid crystal device according to the a pair of first or second reference voltages so as to make a &ggr; correction.

    摘要： A transistor circuit is provided including a driving transistor where conductance between the source and the drain is controlled in response to a supplied voltage, and a compensating transistor where the gate is connected to one of the source and the drain, the compensating transistor being connected so as to supply input signals to the gate of the driving transistor through the source and drain. In a transistor circuit where conductance control in a driving transistor is carried out in response to the voltage of input signals, it is possible to control the conductance by using input signals of a relatively low voltage and a variance in threshold characteristics of driving transistors is compensated. With this transistor circuit, a display panel that can display picture images with reduced uneven brightness is achieved.
