<p>An STN liquid crystal element (20) having a first substrate (1) provided with a reflecting layer (7) and a first electrode (3), a second substrate (2) provided with a second electrode (4), a nematic liquid crystal (6) twist-aligned at a twist angle of 200° to 260° and provided between the two substrates (1, 2), a phase difference plate (12), and polarizer (11) both disposed on the outer side of the second substrate (2). The double refraction Δnd of the STN liquid crystal element (20) is 0.7 to 0.8 νµm. The phase difference representing the double refraction of the phase difference plate (12) is 0.35 to 0.40 ν. The angle at which the phase retardation axis of the phase difference plate (12) intersect the absorption or transmission axis of the polarizer (11) is 30° to 45°. Therefore black display of low reflectance over the whole wavelength region is realized, and high-contrast, high-luminance display is also realized.</p> |
