Abstract
According to the present invention, a method for repairing a defective pixel of a liquid crystal display device is provided. The liquid crystal display device includes a first transparent substrate on an internal surface of which switching elements are formed; a second transparent substrate which is provided being spaced apart from the first transparent substrate and on an internal surface of which a black mask pattern is formed; liquid crystal interposed between the first and the second transparent substrates having a twisted-nematic orientation; and two polarizing plates provided on external surfaces of the first and the second transparent substrates. The method includes the steps of: applying a photosensitive resin composition containing a photosensitive resin and a colorant to the second transparent substrate on a light-outgoing side of the liquid crystal display device; irradiating light rays from an external light source so as to cure the resin composition at a position corresponding to that of a defective pixel on the polarizing plate on the light-outgoing side of the liquid crystal display device, the position being on optical paths of the light rays incident from the exter…
