Electro-optical liquid crystal display device |
摘要 |
An electro-optical display device particularly a liquid crystal display device having a pair of carrier plates spaced apart to form a cavity with each of the carrier plates on a surface facing the cavity being provided with an electrically conductive layer covered by a dielectric layer with the device having the medium, which may be the liquid crystal layer and is switchable between two optically different states, disposed in the cavity, characterized by the conductive layer having a thickness d1 and an index of refraction n1 and each of the dielectric layers having a thickness d2 and a refractive index n2 with the thickness having a range of 0.5 d1</=d1</=1.5 d1 and 0.5 d2</=d2</=1.5 d2, wherein <IMAGE> <IMAGE> with lambda being the mean free wavelength of the operating light, <IMAGE> <IMAGE> with no being the index of refraction of the carrier plate and n3 being the index of refraction of the liquid crystal layer in the idle state.
