Abstract
A first sub-pixel area and a second sub-pixel area that are provided in each of pixel areas so as to sandwich a scanning signal line 2. A first sub-pixel is arranged to include the first sub-pixel area and a section of the counter substrate which section corresponds to the first sub-pixel, area and the second sub-pixel is arranged to include the second sub-pixel area and a section of the counter substrate which section corresponds to the second sub-pixel area. A first alignment control structure is provided in the first sub-pixel and a second alignment control structure is provided in the second sub-pixel. The first alignment control structure (L1 and S1 to S4) provided in one pixel (55x) of two adjacent pixels has a shape obtained by rotating by 180° the first alignment control structure (L11, S11 to S14) provided in the other one pixel (55y) of the two adjacent pixels. This makes it possible to suppress deterioration in viewing angle characteristics caused by disordered alignment along the scanning signal line (2) in a liquid crystal panel in which a plurality of alignment domains can be formed.
