A semiconductor device is capable of suppressing variations of a current or a voltage to be supplied to an external circuit. The semiconductor device has a plurality of unit areas arrayed in one direction, and components in the unit areas are arranged in the same shape and the same layout in the unit areas. A holding capacitor for holding a voltage is surrounded by an interconnect kept at ground potential. Interconnects at ground potential are inserted in areas where reference current interconnects for supplying reference currents to functional blocks (1-bit DCC circuit regions) and gradation digital data interconnects and storage timing signal interconnects cross each other vertically, the interconnects being disposed between these reference current interconnects, gradation digital data interconnects and storage timing signal interconnects.

A display device is comprised of a data line driver, a scan line driver, and a display panel. The display panel is composed of a plurality of drive legs disposed between a current output node and a first node having a fixed potential, each of the drive legs including a drive transistor having a source connected to the first node, a capacitor connected between a gate of the drive transistor and a second node having a fixed potential, a first switch connected between the current output node and a drain of the drive transistor, and a second switch connected between the gate and the drain of the drive transistor. The display panel further includes a data line, a third switch connected between the current output node and the data line, a current-driven element, a fourth switch connected between the current output node and the current-driven element.

A precharge circuit is provided with an N-channel transistor intended for switching. A reference potential is applied to either one of the source and drain of this N-channel transistor. The other of the source and drain is connected to a node. A precharge signal is applied to the gate of the N-channel transistor. The reference potential is set to a precharge output potential for the case of displaying black on a pixel, i.e., the potential when a minimum current flows through a P-channel transistor connected to the other of the source and drain of the N-channel transistor.

A liquid crystal display substrate has a data driver circuit and a gate driver circuit for driving the liquid crystal display integrated thereon together with a common drive circuit, where common voltages VCOMH and VCOML are applied from the outside through a pad. The gate driver circuit is placed to be adjacent to one of the four terminals of the liquid crystal display. The common drive circuit is placed to be adjacent to the terminal opposite to where the gate driver circuit is placed and as close to the pad as possible while having almost the same width as the area of the gate driver circuit. The pad close to where the common drive circuit is placed is used as the pad for applying the common voltages VCOMH and VCOML.
