Abstract: A first electrode 30 for the touch panel is formed on an outer side of a counter substrate 200, and the protection film 210 is formed over the first electrode 30 to cover it. A defect 211 in the protection film 210 is filled in with another protection film 210 by inkjet coating. The surface of the protection film 210 is rubbed to a rough surface finish. The polarization plate 220 is attached to the rough surface of the protection film 210 via an adhesive material 221. Since the defective region is repaired by the formation of the protection film 210, corrosion of the first electrode (wiring) 30 due to the presence of the adhesive material 221 can be prevented, and since the surface of the second protection film 210 is made rough, a resulting increase in adhering surface area enhances the adhesion for attaching the polarization plate 220.

Abstract: In an LCD device, the slope angle of a wall surface of a wall structure (wall-surface slope angle) is varied in accordance with the angle formed between the wall structure and an alignment treatment direction (alignment treatment angle). At places where the alignment treatment angle is small, the wall-surface slope angle is made larger; conversely, at places where the alignment treatment angle is large, the wall-surface slope angle is made smaller.

Abstract: In an LCD device having wall electrodes, four kinds of pixels are used that impart different alignment properties to the liquid crystal molecules. Specifically, the LC molecules are aligned such that: the LC molecules in first pixels twist clockwise and rise in a plus direction; the LC molecules in second pixels twist clockwise and rise in a minus direction; the LC molecules in third pixels twist counterclockwise and rise in the plus direction; and the LC molecules in fourth pixels twist counterclockwise and rise in the minus direction. The pixels of the same type are arranged in rows such that their long sides are adjacent to one another.

Abstract: In an IPS mode liquid crystal display device, a counter electrode is formed flat on a first insulating film. A second insulating film is formed in the peripheral portion of the counter electrode. A third insulating film is formed so as to cover the counter electrode and the second insulating film. A pixel electrode is formed on the third insulating film. The second and third insulating films are present between the pixel electrode and the counter electrode in the periphery of the pixel. The third insulating film is present between the pixel electrode and the counter electrode in the portion other than the peripheral portion of the pixel. An electric field between the pixel electrode and the counter electrode is smaller in the periphery of the pixel than in the vicinity of the center of the pixel, to prevent the occurrence of a domain in the periphery of the pixel.
