The present invention provides a liquid crystal display device capable of reducing a VHR decrease and a residual DC voltage increase after long-term use of the device. The liquid crystal display device includes: a first substrate; a second substrate facing the first substrate; a liquid crystal layer held between the first substrate and the second substrate; and an alignment film disposed on a surface adjacent to the liquid crystal layer of one or both of the first substrate and the second substrate, the one or both of the first substrate and the second substrate with the alignment film disposed thereon including an interlayer insulating film that contains at least one selected from a positive resist and a photoreaction product thereof, the liquid crystal layer containing a liquid crystal material that contains at least one selected from a terphenyl compound and a tetraphenyl compound, the alignment film containing at least one selected from the group consisting of a group represented by the following formula (S-1), a group represented by the following formula (S-2), and a heteroaromatic group.
