Abstract:
A manufacturing method for a liquid crystal display element having a plurality of pixels and including a pair of insulating substrates, each having electrodes formed thereon, an alignment film that is formed in a manner so as to cover the electrodes, a liquid crystal layer that is interpolated between the substrates, each of the plurality of pixels being constituted of the paired electrodes that are aligned face to face with each other between the two substrates and the liquid crystal layer, wherein the liquid crystal layer contains liquid crystal molecules and isotropic micro structural elements that locally give different threshold-value characteristics to the liquid crystal molecules, and wherein the liquid crystal molecules are arranged so as to form smectic layers and the isotropic micro structural elements are arranged between the smectic layers so as to have a striped structure, the manufacturing method comprising the steps of:bonding the insulating substrates to each other after aligning the pair of insulating substrates face to face with each other and after forming the alignment film in a manner so as to cover the electrodes; andfilling a gap between the two substrates with a mixture that is made by mixing a liquid crystal composition with the isotropic micro structural elements that locally give different threshold-value characteristics to the liquid crystal molecules in the liquid crystal composition.
