摘要： A liquid crystal device is constituted by a pair of substrates having mutually opposing electrodes thereon, and a liquid crystal layer disposed between the substrates so as to form a pixel comprising a pair of the opposing electrodes and the liquid crystal layer therebetween. The liquid crystal layer in a pixel is divided into a plurality of regions having mutually different liquid crystal layer thicknesses, and the pixel is constituted so as to show an applied voltage-transmittance characteristic having an improved linearity. More specifically, for example, the liquid crystal layer in a pixel is provided with locally varying thicknesses by forming on a substrate pluralities of stripe-shaped projections and indentations at locally different indentation widths so that the projections have a smaller width in a region having a smaller indentation width than in a region having a larger indentation width.

摘要： A color image forming method provides clear color images with good color balance by thermally controlling a thermosensitive medium, such as polymer liquid crystal. The medium is capable of reversibly assuming optical states of being transparent and of scattering light, and allows picture-element display areas in at least two colors to be composed on a surface thereof. Picture elements within color areas are selected if they correspond to the color whose spectral transmission center is, among those of the colors to be displayed, closest to the longest wavelength involved. Heat is applied such that the maximum haze degree of the selected picture elements is greater than that of picture elements corresponding to any of the other colors.
