Display Device
View Patent ↗According to an aspect, a display device includes: a substrate including a display region and a non-display region surrounding the display region; at least one driver IC including connecting terminals with a first surface fixed to face the non-display region; first wires supplying a signal to the display region; first bumps connected with the first wires; second wires transferring a signal to and from outside; second bumps connected with the second wires; and inspection wires. The connecting terminals of the driver IC include first connecting terminals overlapping the first or second bumps in plan view, and second connecting terminals not overlapping the first or second bumps in plan view. The inspection wires include a connecting conductor between themselves and at least one of the second connecting terminals. The inspection wires are pulled out to an outside of the driver IC in plan view.
1. A display device comprising:
a substrate including a display region and a non-display region that is disposed on a periphery of the display region;
at least one driver IC including a plurality of connecting terminals, and having a first surface that is fixed to face the non-display region;
a plurality of first wires that supply a signal to the display region;
a plurality of first bumps electrically connected with the respective first wires;
a plurality of second wires that input and output a signal from and to an outside;
a plurality of second bumps electrically connected with the respective second wires;
a plurality of inspection wires; and
a plurality of inspection bumps electrically connected with the respective inspection wires, wherein
the connecting terminals of the at least one driver IC comprise a plurality of first connecting terminals overlapping the respective first bumps or the respective second bumps in plan view, and a plurality of second connecting terminals not overlapping the first bumps or the second bumps in plan view,
the inspection wires include a connecting conductor between themselves and at least one of the second connecting terminals, and are pulled out to an outside of the at least one driver IC in plan view, and
a first end of each of the inspection wires is electrically connected with one of the inspection bumps, and a set of second ends of two of the inspection wires overlaps with at least one of the second connecting terminals in plan view.
2. The display device according to claim 1 , wherein
the connecting terminals are arranged to form a plurality of columns in a longitudinal direction of the at least one driver IC in plan view, and
the second connecting terminals overlapping the inspection wires in plan view are arranged in inside columns among the columns in a short direction of the driver IC.
3. The display device according to claim 1 , wherein one of the second connecting terminals, the first connecting terminals, and one of the second connecting terminals are sequentially arranged in a longitudinal direction of the at least one driver IC in plan view.
4. The display device according to claim 1 , wherein the second connecting terminals, the first connecting terminals, and the second connecting terminals are sequentially arranged in a longitudinal direction of the at least one driver IC in plan view.
5. The display device according to claim 1 , wherein the second connecting terminals are closer to a short side of the at least one driver IC than the first connecting terminals are, in a longitudinal direction of the at least one driver IC in plan view.
6. The display device according to claim 1 , wherein eight of the inspection wires are pulled out to an outside of the at least one driver IC in plan view.
7. The display device according to claim 1 , wherein the set of the second ends of two of the inspection wires overlaps two or more of the second connecting terminals in plan view.
