Abstract

First and second data signal lines (S1, s1) are provided correspondingly to one row of pixels, four sub-pixels (1a to 1d) connected to the same scanning signal line (e.g., G1) are included in a pixel (P) to which two storage capacitor lines (Cs1, Cs2) correspond. Two sub-pixels (1a, 1c) of the pixel (P) form the capacitor with one (Cs1) of the two storage capacitor lines. One (1a) of the sub-pixels is connected to the first data signal line (S1) and the other (1c) is connected to the second data signal line (s1). The remaining two sub-pixels (1b, 1d) form the capacitor with the other (Cs2) of the two storage capacitor lines. One (1b) of the sub-pixels is connected to the first data signal line (S1) and the other (1d) is connected to the second data signal line (s1). With the configuration, the four sub-pixels arranged in one pixel are controlled to different luminance levels to allow gradation display.

Description

technical field [0001] The present invention relates to a liquid crystal display device of a pixel division method in which one pixel is constituted by a plurality of sub-pixels, and an active matrix substrate and a liquid crystal panel used in the liquid crystal display device. Background technique [0002] As one method for improving the viewing angle dependence of the γ characteristic of the liquid crystal display device (the difference between the γ characteristic when the liquid crystal display device is viewed from the front and the γ characteristic when the liquid crystal display device is viewed obliquely), it has been proposed to use a plurality of sub-pixels A method of dividing pixels into one pixel (so-called multi-pixel technique) (for example, refer to Patent Document 1). [0003] Figure 46 An equivalent circuit of a liquid crystal display device of a pixel division method is shown. As shown in the figure, this liquid crystal display device is provided with o...
