Abstract: 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. The display apparatus further comprises two data lines (sig) between adjacent pixels and a wiring (DA1,DA2) disposed between two data lines (sig), a first capacitance being formed between the wiring and one of the tyo data lines (sig) and a second capacitance formed between the two data lines (sig).

Abstract: A transistor circuit (100) including a driving transistor (110) where conductance between a source and a drain is controlled in response to voltage, and a compensating transistor (120) where a gate is connected to one of a source and a drain and wherein the compensating transistor is 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.

Abstract: 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 to V4 , 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.

Abstract: 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 gamma 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 an N bits of digital image data DA that indicate gray scale 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 characteristics close to the optical characteristics of the liquid crystal device according to a pair of first or second reference voltage so as to make a gamma correction.

Abstract: 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 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).
