Claim Text:
1. A liquid crystal panel including a display region for displaying image with liquid crystals and a peripheral region located in a periphery of said display region, said liquid crystal panel comprising: a first substrate for controlling said liquid crystal panel; a second substrate facing said first substrate; a sealing material and a connecting member that connect said first substrate and said second substrate; common wiring located in said peripheral region and used to drive said liquid crystal panel; and first ground wiring and second ground wiring located in said peripheral region and connected to a ground potential, wherein on said common wiring, said first ground wiring, and said second ground wiring, an insulating film is located, said sealing material and said connecting member are located apart from each other on said insulating film, said common wiring, said first ground wiring, and said second ground wiring are located apart from each other in said peripheral region, said common wiring and said sealing material are located so as to surround said display region in plan view, said liquid crystals are located in a region defined by said first substrate, said second substrate, and said sealing material, said first ground wiring is located so as to surround said common wiring in plan view, said second ground wiring is located so as to surround said first ground wiring in plan view, said connecting member is located so as to surround said sealing material in plan view, a wiring edge being an edge of said second ground wiring farthest from said display region resides, in plan view, at a position farther from said display region than an edge of said connecting member farthest from said display region, a space is present between said sealing material and said connecting member, said space containing air having a relative dielectric constant smaller than a liquid crystal relative dielectric constant being a relative dielectric constant of said liquid crystals under application of an electric field, a first edge portion being a portion of said first ground wiring closest to said second ground wiring and a second edge portion being a portion of said second ground wiring closest to said first ground wiring are in contact with said space through said insulating film, said sealing material has a relative dielectric constant smaller than the liquid crystal relative dielectric constant, and a third edge portion being a portion of said common wiring closest to said first ground wiring and a fourth edge portion being a portion of said first ground wiring closest to said common wiring are in contact with said sealing material through said insulating film.
