摘要： A capacitor electrode is formed simultaneously with drain bus lines. This capacitor electrode is electrically connected to the contact of two TFT's through the medium of a contact hole. Then, an interlayer insulating film is formed on the entire face and a black matrix of such light blocking metal film as Ti is formed on the interlayer insulating film so as to overlie the channel parts and the contacts of the TFT's and the capacitor electrode. The capacitor electrode, the interlayer insulating film formed thereon, and the black matrix jointly form a capacitor.

摘要： An active-matrix LCD causes no cross-talk even if the capacitance between a given cell and adjacent data lines is large. The LCD has a liquid crystal panel which has data lines arranged in parallel with one another, scan lines arranged orthogonally to the data lines, and liquid crystal cells arranged at the intersections of the data and scan lines, respectively. Each of the cells has a cell electrode and a switching device that is arranged between and connected to the cell electrode and a corresponding one of the data lines. The conduction of the switching device is controlled in response to a scan pulse applied to a corresponding one of the scan lines. The LCD also has a data driver for applying data signals to the data lines, respectively, so that the data signals are written to corresponding ones of the cells, and a scan driver for applying the scan pulse sequentially to the scan lines. The data driver applies positive and negative signals that are opposite to each other with respect to a reference level, to each of the data lines within the period of the scan pulse, to zero an effective voltage applied to each data line. As a result, a voltage sustained by any cell to which data has been written is not affected by voltages successively applied to a data line to which the cell is connected and a data line to which the cell is capacitively connected.

摘要： Disclosed is a liquid-crystal display having the capability of a tablet which offers high image quality and a high response speed. An active matrix type liquid-crystal display having the capability of a tablet comprises: an active matrix type liquid-crystal display composed of a device substrate having a plurality of scan electrodes, a plurality of data electrodes, a plurality of pixel electrodes, and a plurality of switching devices, and an opposed substrate holding a liquid crystal in cooperation with the device substrate; a voltage detector that when brought into contact with a display surface of the liquid-crystal display, detects pulses, which are applied consecutively to the scan electrodes and data electrodes, through electrostatic coupling between the detector and the scan electrodes or between the detector and the data electrodes and that outputs a detected signal; and a position detector for detecting a contact position of the detector on the basis of the detected signal. Herein, the device substrate is situated on the side of the observer of the display. The positions of data electrodes lying in the vicinity of a stylus are detected during a data electrode position detection period defined as a period during which no pulses are applied to scan electrodes. Positions of scan electrodes lying in the vicinity of the stylus are identified by detecting display scanning pulses that are applied consecutively to a plurality of scan electrodes in order to cause the switching devices to conduct consecutively during a display data writing period.
