Claim:
A liquid crystal display device comprising: substrates disposed in opposition to each other with a liquid crystal interposed therebetween; driver chips mounted on one of the substrates in an area other than an area in which the liquid crystal is sealed; the driver chips being electrically connected to signal lines formed to run in an area in which the liquid crystal is sealed, with a stacked structure being interposed between the driver chips and the signal lines, an inorganic material layer and an organic material layer being stacked in that order in the stacked structure; and an alignment mark formed in a layer underlying the stacked structure in the vicinity of each of the driver chips, the inorganic material layer which covers the alignment mark being left in a shape which is coaxially coincident with the alignment mark and is similar to, but larger than, the alignment mark, the vicinity of the inorganic material layer being removed.
