Abstract
(1) A liquid crystal display element including a liquid crystal layer including liquid crystal contained between a pair of substrates and exhibiting a cholesteric phase, wherein an orientation film is arranged on at least one of the paired substrates, and is in contact with the liquid crystal layer, and liquid crystal molecular orientation processing for portions of each orientation film corresponding to pixel regions are effected in a manner different from that effected on at least a portion of a portion corresponding to non-pixel region of the orientation film on at least one of the substrates. (2) A liquid crystal light modulation element including a liquid crystal layer held between a pair of substrate and including a liquid crystal material exhibiting a cholesteric phase in a room temperature and having a peak of a selective reflection wavelength in a visible wavelength range, wherein the liquid crystal layer in the selective reflection state has pixel regions neighboring to the opposite substrates, respectively, and liquid crystal domains in the pixel regions neighboring to at least one of the substrates are in a mixed state of a polydomain state and a monodomain state.

- 62. A liquid crystal light modulation element for performing light modulation by utilizing a focal conic state of liquid crystal molecules included in a liquid crystal layer having a plurality of liquid crystal domains and held between a pair of substrates, wherein the liquid crystal layer includes regions in which helical axes of the liquid crystal molecules of the neighboring liquid crystal domains in the focal conic state extend in directions which are substantially the same and substantially parallel to a substrate surface, and thereby the helical axes of the liquid crystal molecules in the focal conic state extend in regular directions within a plane substantially parallel to the substrate surface.
