A two-terminal non-linear resistive device including a first electrode, a second electrode, and a zinc sulfide layer interposed therebetween. The zinc sulfide layer contains at least one transition metal element as an impurity. The zinc sulfide layer is formed by sputtering using a sintered ZnS target including the transition metal element or a sintered ZnS target including the transition metal sulfide.

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 external light source; and removing an uncured resin composition from a surface of the polarizing plate on the light-outgoing side. According to the method of the invention, a light-shielding portion is easily formed at the position corresponding to that of the defective pixel by patterning.

First display electrodes are formed on a first electrode substrate. Second display electrodes are formed on a second electrode substrate in such a direction as to intersect at right angles with the first display electrodes. In order to obtain a liquid crystal display device provided with a screen having a large contrast ratio, masking films for intermittently masking regions between the display electrodes, formed on at least one of the first electrode substrate, and the second electrode substrate are formed on the display electrodes on the other electrode substrate.
