摘要： An object of the present invention is to provide a transflective type LCD device in which each of a transmissive area and a reflective area can be driven in an OCB mode, and it is possible to prevent lowering of transmittance and reflectance, and to prevent a pixel from darkening in a case where each of the transmissive area and the reflective area is driven in an OCB mode. The liquid crystal display device of the present invention includes, in each pixel (11), a single nucleus generation section for generating a bend nucleus for promoting a transition of liquid crystal molecules of the liquid crystal layer into a bend alignment. Application of a voltage to the liquid crystal molecules of the liquid crystal layer in the transmissive area and the reflective area carries out a transition from a spray alignment into a bend alignment in response to an applied voltage.

摘要： This liquid crystal display device (100) includes: a vertical alignment liquid crystal layer (3); a pixel electrode (11) and a counter electrode (21) arranged on first and second substrates (1, 2), respectively, to front on the liquid crystal layer; and first and second alignment films (12, 22). Each pixel region (10) includes first, second, third and fourth liquid crystal domains (A, B, C, D) in which liquid crystal molecules (3a) are tilted in first, second, third and fourth predetermined directions, respectively, which are defined so that an angle formed between any two of them is approximately equal to an integral multiple of 90 degrees. The first liquid crystal domain is located close to at least a part of edges of the pixel electrode, which includes a first edge portion (EG1) where an azimuthal direction (e1) perpendicular to the part and pointing toward the inside of the pixel electrode defines an angle greater than 90 degrees to the first direction. The first substrate includes a first rib (14) which is arranged in a region corresponding to the first edge portion and under the pixel electrode.

摘要： There are provided areas overlapping at least parts of data bus lines (6) with an intervening insulation layer and one or more holes (3a) arranged in a longitudinal direction of pixel electrodes (3) in areas overlapping the data bus lines (6), in a vertical direction to a TFT substrate. There is also provided an electric potential difference generating section for generating an electric potential difference between the pixel electrodes (3) and the data bus lines (6). Common electrodes (7) for providing auxiliary capacitance are provided on surfaces of the pixel electrodes (3) which do not face the liquid crystal with an insulation layer intervening therebetween. The data bus lines (6) are driven separately from the common electrodes (7). Therefore, nuclei for a bend transition are effectively produced around the holes (3a). The time taken by the bend transition to spread throughout the dot from the nuclei is equal to the time taken to spread the length of the latitudinal direction of each pixel electrode. The bend transition is completed in less time.
