摘要： 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.

摘要： 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.

摘要： A pixel electrode (1) has a frame portion (6) along the entire inner circumference of a pixel (10). The frame portion (6) is provided with a plurality of fine electrodes (7a to 7d) each disposed to form an angle of 45 degrees to the polarization axis of a linear polarizing plate. The pixel electrode (1) has a slit (8) formed in a portion other than the frame portion (6) and the fine electrodes (7a to 7d), i.e., the center portion. When the pixel electrode (1) is applied with a voltage, liquid crystal molecules (4) are oriented in four different directions along the fine electrodes (7a to 7d). Furthermore, by the effects from the frame portion (6) along the entire inner circumference of the pixel (10), the liquid crystal molecules (4) are tilted from the center of the pixel electrode (1) toward the outer circumference of an opposite electrode. That is, the liquid crystal molecules (4) are oriented in the four different directions while tilting from the center of the pixel electrode (1) toward the outer circumference of the opposite electrode.
