摘要： PROBLEM TO BE SOLVED: To decrease a picture frame area which does not contribute to displaying, by forming an electric conductive layer outside of a center line along a running direction of a sealing material, and also avoiding an arrangement of the conductive layer to be opposed to a signal line in the neighborhood of a part of the conductive body connected with an electrode. SOLUTION: An electric conductive body AGP is formed outside a sealing material SL, and a common electrode ITO 2 of a filter substrate side is led to a TFT substrate side via the conductive body AGP. And relating to the common electrode ITO 2, the neighborhood of a part connected with the conductive body AGP is formed as a pattern which is not arranged to oppose a part of a scanning signal line GL. Namely, when each scanning line GL formed within a display part is extended to the outside of the display part, it is arranged so as to be apart from the conductive body AGP by partly providing the extended part with bending part. Thus, it is avoided that the part connected with the conductive body AGP of the common electrode ITO 2 is arranged to oppose the scanning line GL.
