Touch sensor built-in display device and terminal connection structure
View Patent ↗A terminal connection structure includes plural first connection terminals which are arranged side by side in one direction on a first circuit substrate, and plural second connection terminals which are arranged side by side in the one direction on a second resin circuit substrate overlappingly connected to the first circuit substrate and are respectively connected to the plural first connection terminals. Each of the plural second connection terminals includes plural first wirings extending in a direction crossing the one direction, and a second wiring connected to the plural first wirings and extending in the one direction. The second wiring is provided in a region where the second circuit substrate is overlapped and connected to the first circuit substrate.
1. A touch sensor built-in display device comprising:
a TFT substrate in which pixels including thin film transistors are arranged in a matrix form on an insulation substrate;
a plurality of first connection terminals which are arranged side by side in one direction on a first circuit substrate arranged to face the TFT substrate and including touch sensor detection electrodes; and
a plurality of second connection terminals which are arranged side by side in the one direction on a second resin circuit substrate overlappingly connected to the first circuit substrate and are respectively connected to the plurality of first connection terminals, wherein
each of the plurality of second connection terminals includes a plurality of first wirings extending in a direction crossing the one direction, and a second wiring connected to the plurality of first wirings and extending in the one direction, and
the second wiring is provided in a region where the second circuit substrate is overlapped and connected to the first circuit substrate.
2. The touch sensor built-in display device according to claim 1 , wherein the second wiring is positioned in a center portion of three portions obtained by dividing the region where the second circuit substrate is overlapped and connected to the first circuit substrate into three equal parts in a direction perpendicular to the one direction.
3. The touch sensor built-in display device according to claim 1 , further comprising an electric component for controlling driving of the thin film transistors on the TFT substrate, wherein
the electric component is positioned in a region overlapping an inside of an outer edge of the second circuit substrate in plan view, and
the second circuit substrate includes an opening part opening in the region to avoid overlapping with the electric component in plan view.
4. The touch sensor built-in display device according to claim 3 , wherein the first connection terminals are arranged in a region other than a region provided with the opening part in a direction perpendicular to the one direction in the region where the first circuit substrate is overlapped and connected to the second circuit substrate in plan view.
