a spacer main body; and
a coating layer encompassing the spacer main body and comprising a dendrimer,
wherein the dendrimer comprises:
a core part disposed at a central portion of the dendrimer;
a terminal part comprising an aliphatic group compound; and
a linking part connecting the core part with the terminal part.
2. The spacer of claim 1 , wherein the spacer has a spherical shape.
3. A spacer comprising:
a spacer main body; and
a coating layer encompassing the spacer main body and comprising a dendrimer,
wherein the dendrimer comprises:
a core part disposed at a central portion of the dendrimer;
a terminal part comprising an aromatic group compound; and
a linking part connecting the core part with the terminal part.
4. The spacer of claim 3 , wherein the spacer main body comprises polystyrene.
5. The spacer of claim 3 , wherein the spacer main body comprises an acrylic resin layer in contact with the coating layer.
6. The spacer of claim 3 , wherein the spacer has a spherical shape.
7. A spacer comprising:
a spacer main body; and
a coating layer encompassing the spacer main body and comprising a dendrimer,
wherein the spacer main body comprises polystyrene.
8. A spacer comprising:
a spacer main body; and
a coating layer encompassing the spacer main body and comprising a dendrimer,
wherein the spacer main body comprises an acrylic resin layer in contact with the coating layer.
9. A liquid crystal display (LCD) device, comprising:
a first substrate;
a second substrate facing the first substrate;
a liquid crystal layer disposed between the first substrate and the second substrate; and
a spacer maintaining a gap between the first substrate and the second substrate,
wherein the spacer comprises:
a spacer main body; and
a coating layer encompassing the spacer main body and comprising a dendrimer.
10. The LCD device of claim 9 , wherein the first substrate comprises a first alignment layer;
the second substrate comprises a second alignment layer; and
