摘要:
A light control member exhibits strong adhesion between an alignment layer and a bead spacer and includes: a first and second laminate with a substrate and an alignment layer, and which is arranged so that the alignment layer thereof faces the alignment layer of the first laminate; a liquid crystal layer between the first laminate and the second laminate, and the alignment is controlled by driving electrodes on at least one of the first laminate and the second laminate; and a plurality of bead spacers which are arranged within the liquid crystal layer. This light control member is also characterized in that: at least one of the alignment layer of the first laminate and the alignment layer of the second laminate has a plurality of projections that protrude toward the liquid crystal layer; and at least some of the bead spacers are held by the projections.
