Image display having internal wiring with multi-layer structure and manufacturing method thereof having particular wiring connection

摘要

An image display in which a resistance value of internal wiring for inputting a signal and a power supply to a driving IC COG-packaged on an insulating substrate composing a display panel is reduced without enlarging external size of the display panel, and a method of manufacturing the image display. In internal wiring 8 for inputting a signal and a power supply to a driving IC 4 COG-packaged on a first insulating substrate 1 , first layer internal wiring 8 a is composed of a first conductive film forming a scanning line, etc., and second layer internal wiring 8 b is composed of a second conductive film forming a signal line, etc. Connecting wiring 15 for connecting the first layer internal wiring 8 a and the second layer internal wiring 8 b is formed simultaneously with formation of a display electrode, and the internal wiring 8 is formed into a multi-layer structure connected electrically parallel.
