A method of manufacturing a liquid crystal display at a reduced cost is presented. The method entails: preparing an insulating substrate; forming a gate line and a data line on the insulating substrate to define a pixel area; forming a thin film transistor at an intersection of the gate line and the data line; forming A passivation layer on the thin film transistor; positioning a mold having a concavo-convex pattern on the organic passivation layer, pressing the mold, and forming the concavo-convex pattern on the surface of the organic passivation layer. A pixel electrode on the organic passivation layer is formed.
