Patent ID: 7525625

Claim:
A liquid crystal display device, comprising: a wiring substrate; an opposing substrate opposite to the wiring substrate; a sealing member for bonding the wiring substrate to the opposing substrate; a liquid crystal filled in a space defined by the wiring substrate, the opposing substrate, and the sealing member, a plurality of scanning signal lines formed in a display area formed inside the sealing member; a plurality of display signal lines formed in the display area and crossing the scanning signal lines with an insulating film interposed therebetween; a common signal line formed outside the display area and overlapping one side of the sealing member, the common signal line below the one side of the sealing member extends along the one side of the sealing member; a plurality of lead-out lines supplying signals to the plurality of scanning signal lines or the plurality of display signal lines and formed between the common signal line below the one side of the sealing member and the display area to be connected with the plurality of scanning signal lines or the plurality of display signal lines; and the scanning signal lines, the display signal lines, and common signal line being formed on the wiring substrate, and the common signal line including at least two conductive layers with at least one of the conductive layers changing a pattern width below a pattern of the sealing member.
