摘要： A liquid crystal display device and a fabricating method thereof wherein an adhesive force between a seal and a lower plate is improved upon bonding of an upper plate to the lower plate. In high aperture liquid crystal display panels, organic protective films are used to reduce dielectric constants. However, the seal, used when bonding the upper and lower plates of the liquid crystal panel, generally do not adhere well to organic materials. In this invention, holes are generated in the organic protective film so that the seal bonds with inorganic materials such as the lower glass plate or the gate insulating film. A method is also presented to precisely control the amount of the gate insulating film to be etched using the EPD window technique.

摘要： A liquid crystal display and a method of fabricating the same is capable of strengthening adhesion between a sealant and a lower plate in a panel with a high aperture ratio to which an organic protective film is applied. The organic protective film and a gate insulating film are patterned in such a manner that the sealant comes into contact with a substrate directly. Accordingly, the organic protective film or the gate insulating film at the area coated with the sealant is partially or entirely removed to directly contact the sealant with the gate insulating film or the lower glass, thereby strengthening the adhesion between the sealant and the lower plate.
