  • Publication number: 20130027367
    Abstract: In a picture element (100), transmissive electrodes (130, 140) are connected to each other, and reflective electrodes (110, 120) adjacent to the transmissive electrodes are connected to the transmissive electrodes (130, 140), respectively. However, the reflective electrodes (110, 120) are not connected to each other. Alignment controlling structures (111, 121, 131, 141) are provided in regions which correspond to central parts of the respective electrodes, and an alignment controlling structure (151) is provided between the reflective electrodes (110, 120) which are not connected to each other. An alignment of liquid crystals is forcibly made stable in the vicinity of the reflective electrodes by providing the alignment controlling structure (151). It is thus possible to achieve a transflective liquid crystal display device having an excellent display characteristic, such as less roughness and fewer residual images.

  • Publication number: 20130027650
    Abstract: Disclosed is a liquid crystal display device 20 including a display region 11a and a display region 11b. The display region 11a includes pixels 10a provided with, as pixel electrodes, transflective electrodes 15, each including a transmissive electrode 15a that carries out transmissive display, and a reflective electrode 15b that carries out reflective display. The display region 11b includes pixels 10b provided with, as pixel electrodes, transmissive electrodes 16 that carry out transmissive display. The direction in which the long side of the transmissive electrode 15a of the pixel 10a extends is positioned in the same direction in which the long side of the transmissive electrode 16 of the pixel 10b extends. By aligning the long side direction of the transmissive electrode 15a with the long side direction of the transmissive electrode 16, the direction of change in chromaticity in the display region 11a and the direction of change in chromaticity in the display region 11b become the same.

  • Publication number: 20130021231
    Abstract: In a liquid crystal display device (20), a liquid crystal panel (14) is divided into a display region (15a) including a plurality of pixels (10a) and a display region (15b) including a plurality of pixels (10b). A memory circuit (1) is provided to each pixel (10a) included in the display region (15a). The memory circuit (1) is capable of storing a data signal supplied from a signal line (3). As such, writing the data signal, which has been stored in the memory circuit (1), into a pixel electrode (2) allows an image to be displayed in accordance with the data signal. That is, in the display region (15a), it is possible to display an image without supplying image data from the outside via a scanning line (4) and the signal line (3). This allows a reduction in electric power consumption.
