Abstract
A liquid crystal display includes: a first substrate; a second substrate overlapping the first substrate and spaced apart therefrom; a liquid crystal layer between the first substrate and the second substrate and including liquid crystal molecules; a first alignment layer between the first substrate and the liquid crystal layer; and a plurality of protrusions between the first alignment layer and the liquid crystal layer, wherein the first alignment layer includes a photoinitiator, wherein the plurality of protrusions include a polymerization product of the photoinitiator, a reactive mesogen, and a vertical alignment additive, and the vertical alignment additive may be less reactive than the photoinitiator.
