Abstract: A semiconductor circuit includes a first circuit block, a second circuit block, and power wiring lines that supply a plurality of reference potentials. The first circuit block and the second circuit block are connected to a common power wiring line that is one of the power wiring lines and supplies a common reference potential. A width of the common power wiring line in the first circuit block is smaller than a width of the common power wiring line in the second circuit block.

Abstract: To prevent an electrostatic damage on a display device formed with a driving circuit. Protective circuits are provided not only at input terminal parts, but also at intermediate parts of a circuit or at the ends of wiring lines. Otherwise, the protective circuits are provided at the ends of the wiring lines and at the places immediately before and after the input terminals, respectively, and then the circuit is interposed therebetween. Further, the protective circuits are provided around a circuit with a large current consumption.

Abstract: To reduce a voltage applied to a scanning line driving circuit. Buffer circuits respectively connected to gate electrodes of an N-channel transistor and a P-channel transistor which are connected to the scanning lines are provided and driving voltages are made different from each other, such that voltages applied to the buffer circuits are reduced.

Abstract: To enable a common inversion driving even in an LCD having a large size and a high definition. A common capacitance is significantly reduced by making most of scanning lines in a floating state during the common inversion. In addition, the timing for floating the scanning lines is changed depending on the polarity of the common potential. Specifically, if a pixel switching element is an N channel type, the scanning lines are floated when the common potential is high. If the pixel switching element is a P channel type, the scanning lines are floated when the common potential is low.

Abstract: The invention provides an electro-optical device provided including a light reflector having a light diffusion function in a preferable condition while an increase in manufacturing cost thereof is minimized, and also provides an electronic apparatus using the same. The present invention can include an active matrix type reflective or transflective electro-optical device wherein, on a surface of a light reflector of an array substrate, irregularity-forming thin-films can be formed by patterning thin-films composed of the same layers as those forming a underlying protection film, a gate insulation film, a scanning line, a first interlayer insulation film, a data line, and a second interlayer insulation film so as to have predetermined patterns. Since an irregular pattern is formed by steps and irregularity of the irregularity-forming thin-films mentioned above, incident light on an counter substrate can be reflected thereto while being diffused.
