Abstract: A liquid crystal display accommodates a reflective portion with a concavo-convex reflecting pixel electrode for reflecting incident light from the display face side, and a transmissive portion with a transmissive pixel electrode for transmitting light output from the backlight. In a wide viewing angle region, luminance of the reflective portion is greater than the transmissive portion. In other angle regions, luminance of the transmissive portion is greater than the reflective portion. In a wide viewing field mode, the reflective portion and transmissive portion both perform normal display. In the narrow viewing field mode, the transmissive portion performs normal display, while the reflective portion performs cancelling data display, thereby rendering unviewable the display content of the transmissive portion from beyond a certain viewing angle. Thus, a semi-transmissive liquid crystal display device and a portable terminal device is switchable between a narrow viewing field mode and a wide viewing field mode.

Abstract: The liquid crystal display apparatus is provided with a display unit, a video signal driving circuit, a scanning signal driving circuit, a common electrode potential controlling circuit, and a synchronizing circuit. The display unit has a scanning electrode, a video signal electrode, a plurality of pixel electrodes arranged in matrix form, a plurality of switching elements which transmit video signals to the pixel electrodes, and a common electrode. After the scanning signal driving circuit scans the entire scanning electrodes and transmits video signals to the pixel electrodes, the common electrode potential controlling circuit changes the potential of the common electrode into a pulse shape, overdrives video signals, or increases a torque required to return to a state in which no voltage is applied.

Abstract: A liquid crystal display device comprises a liquid crystal panel including sub-pixels and a back light for irradiating light to the back surface of liquid crystal panel. A transmission sub-pixel can be switched into an image display state which can allow irradiated light to exit, and a black display state which does not allow irradiated light to exit. A mirror sub-pixel can be switched between a mirror state which can allow reflected light to exit and a non-mirror state which does not allow reflected light to exit, independently of the transmission sub-pixel. A control unit places each transmission sub-pixel into the image display state or black display state, and places each mirror sub-pixel into the mirror state or non-mirror state.

Abstract: A liquid crystal display element accommodates a reflective portion provided with a concavo-convex reflecting pixel electrode for reflecting incident light from the display face side and displaying information, and a transmissive portion provided with a transmissive pixel electrode for transmitting light that is output from the backlight. The voltages applied to the reflective portion and the transmissive portion are controlled independently. The reflective portion and the transmissive portion have wide viewing angle characteristics. In a wide viewing angle region greater than a certain angle, the luminance of the reflective portion is greater than the luminance of the transmissive portion, whereas in other angle regions the luminance of the transmissive portion is greater than the luminance of the reflective portion. In a wide viewing field mode, the reflective portion and transmissive portion both perform normal display, whereas in the narrow viewing field mode, the transmissive portion performs normal display, while the reflective portion performs cancelling data display, thereby rendering unviewable the display content of the transmissive portion from beyond a certain viewing angle. It is thus possible to provide a semi-transmissive liquid crystal display device and a portable terminal device switchable between a narrow viewing field mode and a wide viewing field mode.

Abstract: A display device is composed of a light source device and a transmissive liquid crystal display panel, and the light source device is provided with a transparent/scattering switching element capable of switching between states in which incident light is transmitted or scattered. Pixels for displaying are disposed in the form of a matrix in the transmissive liquid crystal display panel, and the need for another power supply and signals for the transparent/scattering switching element is eliminated by driving the transparent/scattering switching element using the signals and power supply for driving the pixels. The drive power source of the transparent/scattering switching element for controlling scattering can be made smaller and less costly in a display device that is capable of switching the range of viewing angles.
