    • 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 is disclosed for displaying an image. The liquid crystal display element comprises a liquid crystal display layer in which voltages are applied to a transmissive display unit and a reflective display unit, defined in one pixel, independently of each other, and a light source for irradiating the liquid crystal display layer with light from the back, and a reflection control element disposed between the liquid crystal display layer and light source. The liquid crystal display element is switched between a reflective state and a transmissive state in accordance with a voltage applied to the reflection control element. The liquid crystal display element is switched among a transmissive display mode, a combined reflective/transmissive display mode, and a reflective display mode, by utilizing the transmissive display unit and reflective display unit to display an image independently of each other.
    • 公开了一种用于显示图像的液晶显示元件。 液晶显示元件包括液晶显示层,其中电压施加到彼此独立地定义在一个像素中的透射显示单元和反射显示单元以及用于用光照射液晶显示层的光源 以及设置在液晶显示层和光源之间的反射控制元件。 根据施加到反射控制元件的电压,液晶显示元件在反射状态和透射状态之间切换。 通过利用透射显示单元和反射显示单元彼此独立地显示图像,液晶显示元件在透射显示模式,组合反射/透射显示模式和反射显示模式之间切换。
