Abstract:
1. A method of manufacturing liquid crystal display device comprising the steps of: forming an organic material film having projections and depressions, using a photo-embossing material on an insulating film on an underlying electrode in a thin-film transistor of an active-matrix liquid crystal display device; exposing said insulating film in a contact-hole-forming-area by reducing a thickness of said organic material film by a day etching to said organic material film; and forming a contact hole by a dry etching to the exposed insulating film, wherein the projections and depressions of the organic material film are formed by subjecting the photo-embossing material to a mask and exposure to light, wherein the projections and depressions in the organic material film include a thinnest region corresponding to the contact-hole-forming area.
