1. An image display apparatus, comprising:
- a driving circuit which outputs control signals;
a display panel having pixels which are controlled by said control signals transmitted via predetermined signal lines for a display of an image; and
a plurality of interconnection line devices which include an insulating layer, external connection terminals which are formed on one surface of said insulating layer and connected to said driving circuit, interconnection lines which are formed on another surface of said insulating layer and which are connected to said signal lines at first end portion areas of said interconnection lines, and connection portions which are arranged so as to penetrate through said insulating layer and which connect second end portion areas of said interconnection lines to said external connection terminals,wherein positions of one or more of the connection portions and widths of the interconnection lines are determined such that resistance values of the interconnection lines are approximately equal to each other.
