An (M)th stage of the first through (N)th stages includes a pull-up control part, a pull-up part, a carry holding part, a carry part, and a first pull-down part. The pull-up control part applies a second node signal of a second node to a first node in response to the second node signal. The pull-up part outputs a clock signal as an (M)th gate output signal in response to the first node signal. The carry holding part applies the (M)th gate output signal to the second node in response to the (M)th gate output signal. The carry part outputs the clock signal as an (M)th carry signal in response to the first node signal. The first pull-down part pulls down the (M)th gate output signal to a first off voltage.

  • Patent number: RE46497
    Abstract: A liquid crystal display apparatus includes a plurality of data lines each having a plurality of straight line portions and a plurality of curved portions connected to a plurality of the straight line portions; a plurality of gate lines intersecting the data lines; thin film transistors connected to the data lines and the gate lines; and pixel electrodes connected to the thin film transistors. Accordingly, even in a case where driver inversion becomes column inversion, apparent inversion can become dot inversion. As a result, it is possible to eliminate transverse line flicker and to increase a charging rate of pixels. In addition, uniformity of the pixels can be maintained, so that the inversion driving schemes can be applied to a PVA mode. As a result, it is possible to obtain a wide viewing angle and to improve side or lateral visibility.
