    摘要: A display panel includes (i) a first substrate and a second substrate, which face each other, (ii) a medium layer being sandwiched between the first and second substrate, and (iii) first electrodes and second electrodes being provided on that side of the first substrate which faces the second substrate, the display panel performing display operation by generating an electric field between the first and second electrodes. The display panel is configured such that the medium layer comprises a medium that is optically isotropic when no electric field is applied thereon, and whose optical anisotropy magnitude is changeable by and according to the electric field applied thereon; and the first and second electrodes are transparent electrodes, and a distance between the first and the second electrodes is shorter than a distance between the first substrate and second substrate. This configuration attains gives the display panel high response speed and high transmissivity.

    摘要: A display element has an arrangement that allows the pixel to have at least two domains in which the medium shows optical anisotropies of different directions when a force (for example, an electric field) is applied or when no force is applied. It is preferable that directions of the optical anisotropies occurred in the respective domains when the electric field is applied respectively have 45 degrees±10 degrees with absorption axes of polarizers, and that the directions of the optical anisotropies occurred in the respective domains when the electric field is applied make 90 degrees±20 degrees.

    摘要: A display element of the present invention includes: a pair of substrates which are opposed to each other; and a substance layer, which is sandwiched between the substrates, exhibiting an optical isotropy when no electric field is applied, while exhibiting an optical anisotropy when an electric field is applied, and the display element performs display operation by applying an electric field to between the substrates. The substance layer includes a liquid crystalline medium exhibiting a nematic liquid crystal phase, and it is Δn×|Δ∈|≧1.9, where Δn is a refractive index anisotropy at 550 nm in a nematic phase of the liquid crystalline medium, and |Δ∈| is an absolute value of a dielectric anisotropy at 1 kHz in the nematic phase of the liquid crystalline medium. The display element and a display device including the display element realize a fast response speed and a low driving voltage and driving in a wide temperature range.
