摘要： A liquid crystal display includes first and second opposing spaced insulating substrates, pixel electrodes formed on the first substrate, a common electrode formed on at least one of the first and second substrates, and a liquid crystal layer interposed there between the first substrate and the second substrate. In this structure, each pixel electrode is divided into a main-pixel electrode and a sub-pixel electrode, to which different signal voltages are individually applied at the same gray scale. Further, a signal voltage to be applied to the sub-pixel electrodes is determined by a gamma value satisfying the following equation: Gamma K=(current gray scale/maximum gray scale)f F(Gray Scale)=α×(maximum gray scale/current gray scale), wherein α is a constant.

摘要： In an optical intensity modulator, and a fabrication method thereof, the optical intensity modulator includes a substrate made of a predetermined material, an arc shaped optical waveguide formed on the substrate, and an electrode formed on the optical waveguide such that the electrode is in alignment with the optical waveguide, the refractive index of the optical waveguide being changed in accordance with an intensity of an electric field applied to the electrode, and an optical wave passing a predetermined location of the optical waveguide being radiated into the substrate due to the changed refractive index. Accordingly, a large modulation depth can be obtained from only a small refractive index variation by using the radiation loss characteristics of the arc shaped waveguide.
