Display device

摘要

A display device includes a display panel, a light shielding plate having an opening, a protective plate, and a coordinate input device having a transparent substrate, and a first flexible interconnect substrate. The coordinate input device is disposed on the display panel at the side of a display screen, and each of the light shielding plate and the protective plate is arranged on the coordinate input device on the opposite side of the display panel. The coordinate input device has first signal interconnects and a second signal interconnect disposed outside the first signal interconnects but near a peripheral edge of the transparent substrate. The second signal interconnect is formed of a thin conductive film disposed along a peripheral edge portion of the transparent substrate, and is disposed along the peripheral edge of three sides of the transparent substrate.

1. A display device comprising:
a coordinate input substrate having detection electrodes disposed in a detection region, and first interconnects outside the detection region; a protective plate on the coordinate input substrate; a light shielding material which has an opening and is disposed between the coordinate input substrate and the protective plate; and a first flexible substrate electrically connected to the coordinate input substrate, wherein the coordinate input substrate has a second interconnect, a first electrode, and a second electrode, wherein the second interconnect surrounds the detection region and is formed outside the first interconnects, wherein the first electrode is formed at one end of the second interconnect, wherein the second electrode is formed at the other end of the second interconnect, wherein the second interconnect is disposed along a peripheral edge of at least three sides of the coordinate input substrate, wherein a display region is surrounded by the second interconnect, wherein the first electrode is electrically connected with a third electrode on the first flexible substrate, or the second electrode is electrically connected with a fourth electrode on the first flexible substrate, wherein the opening of the light shielding material is larger than the display region and surrounds the display region, and wherein the light shielding material overlaps the second interconnect along the peripheral edge of at least the three sides of the coordinate input substrate in a plan view.
