Abstract:
1. A liquid crystal display element comprising: a first substrate on which a first electrode is provided; a second substrate on which a second electrode is provided; a liquid crystal layer provided between the first substrate and the second substrate; and a plurality of first wall surface structures arranged to define a plurality of pixels in the liquid crystal layer, wherein each gap between each two adjacent first wall surface structures defines an opening which links two contiguous pixels, a plurality of openings defined by gaps between the plurality of first wall surface structures are arranged nonlinearly in a first direction along which the first electrode runs and which is parallel to a surface plane of the first substrate, in a second direction along which the second electrode runs and which is parallel to a surface plane of the second substrate, or in both the first direction and the second direction, the plurality of first wall surface structures include the first wall surface structures of a first type and the first wall surface structures of a second type, each first wall surface structure of the first type has a cross-shaped cross section where an arm of a first length along the first direction and an arm of a second length along the second direction cross, each first wall surface structure of the second type has a cross-shaped cross section where an arm of the second length along the first direction and an arm of the first length along the second direction cross, and the first length and the second length are different from each other.
