PURPOSE:To eliminate the coloring of a display and to increase a visual angle by using a high polymer drawn film or liquid crystal cell which has optically negative uniaxial performance as an optical anisotropic body. CONSTITUTION:This element is equipped with the liquid crystal cell 2 formed by sandwiching homogeneously oriented liquid crystal between two opposite electrode substrates 6 and 7, the optical anisotropic body 3 which consists of at least one layer except the liquid crystal, and a couple of polarizing plates 1 and 4 arranged on both sides of them. Then the optical anisotropic body 3 is so constituted that one refractive index N3e among three principal refractive indexes N1o, N2o, and N3e that the optical anisotropic body 3 has is smaller than other two refractive indexes N1o and N2o and the axis corresponding to the refractive index N3e is nearly parallel to the substrate surface of the liquid crystal cell 2. Thus, the high polymer drawn film or liquid crystal cell which has the negative uniaxial performance is used as the optical anisotropic body 3. Consequently, the liquid crystal electrooptic element which has a wide view angle and is small in the coloring of display is obtained. |
