摘要： A display apparatus is provided which is 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 including a light-emission element, such as an electroluminescence element or an LED element, are arranged on both sides of common power-feed lines so that the number of common power-feed lines is reduced. Further, the polarity of a driving current flowing between the pixels and the light-emission element is inverted so that the amount of current flowing through the common power-supply lines 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 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： The invention provides a display device in which parasitic capacitance associated with data lines and driving circuits is prevented using a bank layer whose primary purpose is to define areas on a substrate in which an organic semiconductor film is formed. When the organic semiconductor film for forming a luminescent element such as an electroluminescent element or an LED is formed is formed in pixel regions (7), the organic semiconductor film is formed in the areas surrounded by the bank layer (bank) formed of a black resist. The bank layer (bank) is also formed between an opposite electrode (op) and data lines (sig) for supplying an image signal to first TFTs (20) and holding capacitors (cap) in the pixel regions (7) thereby preventing parasitic capacitance associated with the data lines (sig).

摘要： A video signal is sampled by sequential switches (104), etc. and the voltage held in capacitors (150) after passing through switches (110). Next, switches (120), (130) turn on, the hold for capacitor (152) is carried out, and that voltage buffered by analog buffer (170), then output. The switch on-off control is performed by means of lines L1 and L2. The control of the supply voltage is performed by V1.sup.+ to V4.sup.+, and the polarity of analog buffers (170), (172), etc. is controlled. By means of the switch on-off control and the supply voltage control, four driving methods for alternating liquid crystal driving can be realized. Further, the analog buffers are composed of TFTs; and positive and negative polarity inversion can be performed through supply voltage shift.
