Abstract

A multipanel liquid crystal display device and a method of manufacturing such a device is disclosed. The liquid crystal display device comprises two or four panels of square shape each including a first plate of square shape. These two or four first plates are disposed in such a positional relation that at least two orthogonally crossing sides of each of the plates are not adjoined by any one of the remaining plates thereby forming a planar assembly lying in the plane. One of the major surfaces of each of the first plates provides a display region except marginal edges adjacent to the at least two orthogonally crossing sides not adjoined by any one of the remaining plates, and picture element electrodes arranged in a matrix pattern are previously provided on this display region. Further, in each first plate, electrode lead-out terminals connected to the respective picture element electrodes are previously disposed along the marginal edges adjacent to the two sides described above. The liquid crystal display device further comprises a transparent second plate having a common electrode previously disposed on its surface opposite to the display surface of the first plate assembly, the common electrode having an area large enough to cover at least the entire display region of the first plate assembly, a third plate, means for fixing the first plate assembly relative to the second and third plates so as to locate the first plate assembly between the second plate and the third plate, and a liquid crystal material enclosed at least between the second plate and the first plate assembly.
