  • Publication number: 20100255222
    Abstract: A display element that includes substrates each having a thin film layer formed by applying a thin film layer composition thereon by an ink-jet method, in which, in the formation of the thin film layers, streaky display unevenness does not develop along a direction in which an ink-jet head discharges the composition having the shape of dots aligned on straight lines from the nozzles. In the liquid crystal display element 1 including an array substrate 5 including an alignment film 8, and a color filter substrate 3 including an alignment film 7, the substrates 5 and 3 being used in a pair, the dots on the alignment films 7 and 8 are aligned such that an interval between the straight lines on the alignment film 8 is displaced by half an interval from an interval between the straight lines on the alignment film 7.

  • Patent number: 7564510
    Abstract: A pixel 3 includes a pixel electrode 31 and opposed electrodes 32 for generating electric fields between a pair of substrates in directions substantially parallel to the substrates and also includes two regions S1 and S2 defined by the pixel electrode 31 and the opposed electrodes 32. The electric fields are generated in the adjacent regions S1 and S2 in opposite directions. A liquid crystal layer has a structure in which a slow axis indicating a refractive-index anisotropy as viewed in a direction normal to the substrates is vertical to the electric-field direction without an application of an electric field whereas slow axis in these regions S1 and S2 rotate about axes normal to the substrates in opposite directions. In this manner, the viewing angle of a liquid crystal display device is increased and coloring is prevented. In addition, the response speed and the aperture ratio are enhanced.
