Liquid crystal display and manufacturing method thereof

A method of manufacturing a liquid crystal display, the method comprising:

• providing a first display panel comprising a first alignment layer comprising an alignment polymer and a reactive mesogen, wherein the alignment polymer comprises a main chain and a photo-reactive group connected as a side chain to the main chain;
• providing a second display panel comprising a second alignment layer;
• forming a liquid crystal layer comprising a liquid crystal molecule and a photoreaction initiator between the first display panel and the second display panel;
• eluting the reactive mesogen from the first alignment layer into the liquid crystal layer by applying heat;
• and
• irradiating ultraviolet light onto the first display panel, the second display panel, and the liquid crystal layer,
• wherein in the irradiating of the ultraviolet light, a plurality of protrusions comprising an orientation polymer comprising a polymerized reactive mesogen, are formed between the first alignment layer and the liquid crystal layer,
• wherein the orientation polymer and the alignment polymer are different polymers,
• wherein the photo-reactive group comprises a structure of at least one compound represented by the following Chemical Formulas 3 to 15:
• wherein the photoreaction initiator comprises at least one compound represented by the Chemical Formulas 3 to 15, and
• wherein a liquid crystal molecule adjacent to the first alignment layer has a pretilt angle greater than a liquid crystal molecule adjacent to the second alignment layer.
