Abstract:
1. A display device, comprising: a flexible substrate; and an electric circuit board that is connected electrically with the flexible substrate, wherein the flexible substrate is made of a flexible base film, and includes wiring patterns and connection terminals that are formed at end portions of the wiring patterns, the electric circuit board includes metal lines, lead-out lines that are led out from the metal lines, and electrode terminals that are formed at tips of the lead-out lines, the connection terminals are connected electrically with the electrode terminals of the electric circuit board, the electrode terminals include a first electrode terminal that is connected with one of the lead-out lines, and a plurality of second electrode terminals that are branched from one of the lead-out lines, the connection terminals include a first connection terminal that is connected with one of the wiring patterns, and a second connection terminal that is joined from a plurality of the wiring patterns, and the second connection terminal and a plurality of the second electrode terminals are opposed to each other on the electric circuit board in a thickness direction of the electric circuit board, wherein the width of the second connection terminal is narrower than the width of the lead-out line that is connected with the second electrode terminals to be connected with the second connection terminal, and the number of wiring patterns of the second connection terminal coincides with the number of branches of the second electrode terminal.
