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.

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.

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.
