Abstract:
A liquid-crystal-panel evaluating method for optically evaluating a liquid crystal panel comprising:making polarized light in a predetermined state be incident upon the liquid crystal panel; and increasing a ratio of a polarized component of specularly reflected light, formed as a result of reflection of the incident light, transmitted through a liquid crystal layer of the liquid crystal panel to form detection light in order to evaluate the panel based on the detection light; wherein the polarized light is composed almost exclusively of a polarized component including a first vibration plane, and the detection light includes a component of the specularly reflected light having the polarized component with the first vibration plane eliminated therefrom, wherein the detection light also includes a polarized component including a second vibration plane that is virtually orthogonal to the first vibration plane, the polarized component including the second vibration plane extracted from the specularly reflected light.
