 Liquid-crystal display + small size and weight + no visible flicker, interference from magnetic fields + no problems with image geometry and clarity + low power consumption - can display a clear image only with one ("normal") resolution - low contrast and depth of black color - dependence of the contrast on the viewing angle - problem of defective pixels
