TERMINAL CONNECTION STRUCTURE OF SUBSTRATE

PROBLEM TO BE SOLVED: To provide a terminal connection structure of substrate, in which exfoliation of connection terminals, the occurrence of abnormal electrical connection and damages to the coupling of a film substrate and a substrate are prevented, even if stress is generated at a part where the terminal part of the film substrate is bonded to the terminal part of the substrate by theremocompression, or the like, and shift in the position relation of the opposite connection terminals can be found visually easily, at connecting time. SOLUTION: Bonding strength between outermost connection terminals 2d and 4d is enhanced, by widening the outermost connection terminals 2d and 4d susceptible to concentration of stress, thus preventing exfoliation of the outermost connection terminals 2d and 4d due to stress, occurrence of abnormal electrical connection, and damages to the coupling of a film substrate 1 and a substrate 3. Since the outermost connection terminals 2d and 4d are widened, the shift in the position relation of the opposite connection terminals can easily be found visually.
