Δo The current mainstream among these liquid crystal display cells is a TN cell, which is a type of field effect cell. In this TN type cell, as reported by G.Bauer in Mol.Cryst.Liq.Cryst. 63 45 (1981), interference fringes occur on the cell surface, which impairs the appearance of the cell. In order to prevent this, it is necessary to set the product of the refractive index anisotropy Δ o of the liquid crystal material filled in the cell and the cell thickness d μm to a certain value. In the liquid crystal display cell used practically,
