A field-effect liquid-crystal type display device employing a twisted alignment method is provided with a pair of electrode glass plates spaced apart from each other and a field-effect type liquid crystal with a positive dielectric anisotropy loaded in the space defined by the plates, the plates being disposed in such a manner that an angle formed by the alignment treatment directions of the plates is changed a proper angle from 90.degree., so that the twisting direction of molecules in the liquid crystal is unified and the liquid crystal type display device is improved to show homogeneity, and thus to reduce the number of dirty domains or spots in display.
