Abstract

PURPOSE:To eliminate visual angle dependency and make a display easy to see by disposing the liquid crystal molecules adjacent to both surfaces of the electrode substrate sandwiched by two layers of thin layers of positive dielectric anisotropic nematic liquid crystals contg. dichromatic dyes by intersecting their long axis directions mutually orthogonally. CONSTITUTION:The surfaces of the electrode substrates 11, 12 of an upper layer of positive dielectric anisotropic nematic liquid crystals 10 contg. dichromatic dyes are rubbed transversely and the surfaces of the electrode substrates 12, 14 of a lower layer 13 of positive dielectric anisotropic nematic liquid crystals contg. dichromatic dyes are rubbed longitudinally, whereby the liquid crystal molecules adjacent to both surfaces of the substrate 12 are oriented by intersecting their long axis directions mutually orthogonally. When an electric field is applied to the liquid crystal layer 10, the characters of the lower liquid crystal layer 13 are displayed, and when an electric field is applied to the liquid crystal layer 13, the characters of the layer 10 are displayed. Thereby, visible light is efficiently absorbed in the two layers and the relatively dark ground is made.
