Problems solved by technology

[0008] However, three transistors (one transistor for writing in the current stage and two transistors for discharging each pixel electrode of the next stage) transistors are connected to one scanning signal line per pixel. Figure 40 The composition of the present invention has the following problems: the scanning signal line is excessively loaded, and it is not suitable for a large-scale high-definition liquid crystal display device or a high-speed drive (for example, a double-speed drive) liquid crystal display device.

Abstract

The present invention relates to a capacitively-coupled pixel-division liquid crystal display device. A liquid crystal display device includes rows and columns of pixels each containing two pixel electrodes connected to each other via a capacitor, each of the columns of pixels being provided with two data signal lines (Sx, Sy) corresponding thereto, each of the rows of pixels being provided with a single scanning line (Gn) and a single sub-signal line (gn) both corresponding thereto, one of the two pixel electrodes of each of the pixels belonging to the columns of pixels and the rows of pixels being connected to the data signal line (Sx) via a transistor connected to the scanning signal line (Gn), the other pixel electrode being connected to a retention capacitor wire via a transistor connected to the sub-signal line (gn), two scanning signal lines (Gn, G(n+1)) corresponding to two rows of pixels upstream of a scanning direction among four consecutive rows of pixels and two sub-signal lines (g(n+2), g(n+3)) corresponding to two rows of pixels downstream of the scanning direction among the four consecutive rows of pixels being simultaneously selected. The present invention makes it possible to achieve suppression of pixel image sticking and a reduction in load on the scanning signal lines.

Description

technical field [0001] The present invention relates to a liquid crystal display device, an active matrix substrate, and the like of a capacitive coupling type pixel division method. Background technique [0002] In an active matrix substrate of a capacitively coupled pixel division method, two pixel electrodes capacitively coupled to each other are provided in one pixel, and one pixel electrode is connected to a data signal line via a transistor. In this configuration, it is easy to apply a DC voltage to the other pixel electrode (the pixel electrode not connected to the data signal line) that is electrically floating, and this becomes a factor of image sticking of the pixel. [0003] In this regard, in Patent Document 1 (refer to Figure 40 ) discloses the following configuration: the two transistors 421 and 422 for discharge are connected to the scanning signal line 112 (n-1) of the previous stage, and when scanning the previous stage (before scanning the current stage), ...
