发明名称 Liquid crystal display device.
摘要 <p>The invention relates to a liquid crystal display device wherein phase difference plates (2,4) equal in retardation value, being composed of uniaxial polymer film or the like, are disposed symmetrically at the front side and back side of an STN liquid crystal panel (3), and the wavelength dispersion is made nearly ideal. As a result, the phase difference is compensated over the entire wavelength region, and the azimuth angles of the exit ellipsoidal polarization are aligned, so that a colorless display and high contrast may be realized at the same time.</p>
