Patent ID: 7875477

Claim:
A method of manufacturing a display device comprising: preparing an insulating substrate by: (a) manufacturing a plurality of insulating substrates from a mother substrate, the mother substrate having a plurality of substrate portions separated by a plurality of peripheral portions, wherein the plurality of substrate portions are used as the plurality of insulating substrates; (b) forming a passivation layer removing portion in a mold, wherein the passivation layer removing portion of the mold is pressed toward the peripheral portion of the mother substrate; forming a gate line and a data line on the insulating substrate, the gate line and the data line extending in directions that are perpendicular to each other while remaining insulated from each other, the gate line and the data line disposed at a pixel area; forming a thin film transistor at an intersection of the gate line and the data line; forming an organic passivation layer on the thin film transistor; positioning the mold having a concavo-convex pattern such that the concavo-convex pattern is aligned with the pixel area on the organic passivation layer; pressing the mold against the organic passivation layer to form the concavo-convex pattern on the surface of the organic passivation layer; and forming a pixel electrode on the concavo-convex pattern of the organic passivation layer.
