Claim:
1. A display device comprising: a substrate; a thin film transistor positioned on the substrate; a pixel electrode connected to the thin film transistor; an alignment layer positioned on the pixel electrode; a liquid crystal layer including liquid crystal molecules formed on the alignment layer and positioned in a plurality of microcavities; a roof layer positioned such that the roof layer is spaced apart from the pixel electrode with a microcavity interposed therebetween; and an overcoat positioned on the roof layer and covering a trench positioned between the plurality of microcavities, wherein in the liquid crystal layer, a pre-tilt angle manifestation group positioned to be adjacent to the alignment layer is formed, and the pre-tilt angle manifestation group comprises a polymer of a compound represented by the following Chemical Formula 1: wherein L is each independently a single bond, an alkylene group, or an ester group, R is each independently an alkenyl group or a vinyl group, A is a trivalent or tetravalent aliphatic organic group or alicyclic organic group, a sum of n1 to n4 is 3 or 4, and n1 to n4 are each 0 or 1; and wherein the pre-tilt angle manifestation group further comprises a polymerization reaction group, and the polymerization reaction group comprises a compound represented by the following Chemical Formula 3:
