摘要： A shield electrode is provided in the vicinity of a pixel electrode and source bus lines. The shield electrode may be provided in the same layer as gate bus lines, or in the same layer as the source bus lines. The shield electrode may be surrounded by an insulating material, or may be connected to a line other than the source bus lines. By providing the shield electrode, it is possible to reduce a source-drain parasitic capacitance between a pixel electrode and a source bus line.

摘要： In one embodiment of the invention, a capacitor is provided between a node and a negative-side input terminal of a differential amplifier. A switch SW11 is provided between the negative-side input terminal and an output terminal of the differential amplifier. A switch SW12 is provided between the node and the output terminal of the differential amplifier. Switches SW13 to SW16 are provided for switching between a voltage of the node and a positive-side input voltage of the differential amplifier. The switches SW11 and SW12 are on during different periods. In a positive polarity mode, the switches SW13 and SW16 are when the switch SW11 is on while the switch SW16 is on when the switch SW12 is on. In a negative polarity mode, the switches SW14 and SW15 are on when the switch SW11 is on while the switch SW16 is on when the switch SW12 is on. Thus, two types of gradation voltages each required for AC drive of a liquid crystal can be generated with a small circuit scale.

摘要： A display device of the present invention comprises: a source line; a pixel electrode; a first TFT for switching an electrical connection between the source line and the pixel electrode; and a second TFT as a spare. The second TFT includes a semiconductor film and a gate electrode. The semiconductor film includes a source electrode and a drain electrode. The gate electrode is provided on the semiconductor film with a gate insulation film interposed therebetween. The display device includes an interlayer insulation film between the source line and the semiconductor film of the second TFT. The interlayer insulation film is thicker than the gate insulation film. When the first TFT is unusable, a contact hole is formed in the interlayer insulation film such that the source line is electrically connected to the source electrode, whereby the electrical connection between the source line and the pixel electrode is rendered switchable by the second TFT.

摘要： In a photosensor in the pixel region of an active matrix substrate, the potential of a storage node is read out to output wiring as sensor circuit output, the potential of the storage node having changed in accordance with the amount of light received by a photodetection element in a sensing period, the sensing period being from when a reset signal (RS) is supplied until when a readout signal (RW) is supplied. A sensor startup period whose length is greater than or equal to the length of the sensing period is provided after a sensor data unnecessary period in which the sensor circuit output is not necessary, and furthermore before a valid sensor data period in which the sensor circuit output is necessary, and the sensor circuit output is read out in the valid sensor data period from the photosensor to which the reset signal was applied in the sensor startup period.

摘要： In a multi-gap semi-transmissive liquid crystal display device, the width of a black matrix (6) is made larger above the region between adjacent ITO transparent electrodes (3) and is made smaller above the region between adjacent Al reflective electrodes (4). This enables a transmissive portion to offer a display with high contrast that does not suffer from afterimage or the like by shielding light from the domain lying between the adjacent pixels, and the reflective portion to offer a brighter display by increasing the aperture ratio thereof by making the black matrix width as small as possible or forming no black matrix.

摘要： In one embodiment of the present invention, a voltage source is disclosed including a lower output impedance is connected to a capacitive load via a switch element and a voltage source including a higher output impedance is connected to the capacitive load via a switch element. Until a potential of an output terminal attains a reference potential, a comparator keeps the switch element in an ON state so that the voltage source writes a potential onto the capacitive load. When the potential of the output terminal exceeds the reference potential, the comparator causes the switch element to be in an ON state so that the voltage source writes a potential onto the capacitive load so as to have a predetermined potential.
