    • A transflective liquid crystal display with uniform cell gap configuration throughout the transmissive and the reflective display region is invented. Mutually complementary common electrode pattern and reflector pattern or mutually complementary ITO pixel electrode pattern and reflector pattern produce an electric field in the transmissive display region that has a uniform longitudinal field and an electric field in the reflective display region that is a fringing field. An initially vertically aligned negative dielectric anisotropic nematic liquid crystal material between the electrodes forms a smaller tilt angle with respect to the substrate normal in the reflective display region while a larger tilt angle with respect to the substrate normal in the transmissive display region. Consequently, the ambient incident light experiences smaller phase retardation in the reflective display region while the light from the backlight source experiences larger phase retardation. Since the ambient light passes through the reflective display region twice while the light from the backlight source passes through the transmissive display region only once, by properly designing the electrodes and the reflector width, the light from both ambient light source and backlight source will experience almost the same phase retardation in both reflective and transmissive display regions. As a result, the electro-optical performance curves of both-transmissive display mode and reflective display mode overlap.
    • 发明了在整个透射和反射显示区域中具有均匀的单元间隙配置的半透射型液晶显示器。 相互互补的公共电极图案和反射器图案或互补的ITO像素电极图案和反射器图案在透射显示区域中产生在反射显示区域中具有均匀的纵向场和电场的电场,该电场是边缘场。 电极之间的初始垂直排列的负介电各向异性向列型液晶材料在反射显示区域中相对于衬底法线形成较小的倾斜角,而在透射显示区域中相对于衬底的倾斜角相对于衬底法定。 因此,环境入射光在反射显示区域中经历较小的相位延迟,而来自背光源的光经历较大的相位延迟。 由于环境光通过反射显示区域两次,而来自背光源的光仅通过透射显示区域一次,通过适当地设计电极和反射器宽度,来自环境光源和背光源的光将经历几乎 在反射和透射显示区域中相同的相位延迟。 结果,双透射显示模式和反射显示模式的电光性能曲线重叠。
