    • 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.
    • 液晶显示器容纳具有用于反射来自显示面侧的入射光的凹凸反射像素电极的反射部分和具有用于透射从背光源输出的光的透射像素电极的透射部分。 在宽视角区域中,反射部分的亮度大于透射部分。 在其他角度区域中,透射部分的亮度大于反射部分。 在宽视野模式中,反射部分和透射部分均执行正常显示。 在窄视野模式中,透射部分执行正常显示,而反射部分执行取消数据显示,从而使透视部分的显示内容超过一定视角。 因此,半透射型液晶显示装置和便携式终端装置能够在窄视场模式和宽视野模式之间切换。

    • 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.
