ABSTRACT:
The present invention provides a liquid crystal display device that can eliminate an electrostatic discharge problem resulting from a high dielectric constant filler that is appropriate for improved shape stability of a sealing material. More particularly, the present invention is directed to sealing material 40 disposed between an array substrate 10 and an opposing substrate 12 contains a resin material and an inorganic dielectric filler. The filler consists of talc, mica or alumina having a dielectric constant higher than that of the resin material, and has plate-like or variable shape. The array substrate 10 includes gate lines 26 and data lines 24 that are separated by an insulating layer 28. The gate lines 26 or the data lines 24 that lie on the surface of the insulating layer 28 on the side of the sealing material 40 (e.g., the data lines 24) are led to the surface of the insulating layer 28 opposite the sealing material 40 through vias 62 in the insulating layer 28 and conductive lines 60, before the data lines 24 reach the location of the sealing material 40. Therefore, at the location of the sealing material 40, the data lines 24 are separated from the sealing material 40 by the insulating layer 28, and an electrostatic discharge that occurs through the sealing material 40 can be prevented.
