摘要： The present invention discloses a liquid crystal display device which is arranged by: (A) the first substrate including a plurality of scanning lines and a plurality of signal lines arranged in a matrix form; a common signal line extended in parallel to one of the scanning lines and the signal lines, for applying a reference potential thereto; a pixel electrode; and a thin-film transistor having a source electrode connected to the pixel electrode, a drain electrode connected to the signal line, and a gate electrode connected to the scanning line, the thin-film transistor being formed in an intersection portion between the scanning line and the signal line; (B) the second substrate including a black matrix layer and positioned opposite to the first substrate with sandwiching a liquid crystal layer between the first substrate and the second substrate; and (C) an insulating layer sandwiched between the pixel electrode of the first substrate and the scanning line. While a voltage is applied between the common signal line and the pixel electrode to thereby produce an electric field, a direction of a molecular axis of liquid crystal molecules contained in the liquid crystal layer is rotated within a plane located in parallel to the first substrate so as to perform a liquid crystal display; and further said pixel electrode of the first substrate covers a portion of the scanning lines located in a region other than such a region where the thin-film transistor is formed.

摘要： An active matrix liquid display system where two scanning lines are successively selected within one horizontal scanning period, by which display voltages are written on pixels lined up in a horizontal direction, and the voltage supplied to a signal line when an even number display pixel is selected and the voltage supplied to a signal line when an odd number display pixel is selected are switched according to a gradation voltage generated from a gradation power source. Accordingly, when there is implemented a dot inversion drive in the active matrix liquid display system where there are less number of signal line drive circuits, and when a former stage pixel is subjected to modulation due to interpixel parasitic capacitance, it is possible to equalize an electric voltage of the former stage pixel being modulated as a latter stage pixel is being written with an electric voltage of the latter stage pixel, owing to revision of a gradation voltage of the former stage pixel.
