Touch panel

摘要

A touch panel includes a transparent plate, an upper substrate having an upper surface situated on a lower surface of the transparent plate and stacked on the transparent plate in a downward direction, an upper conductive layer provided between the lower surface of the transparent plate and the lower surface of the upper substrate, a lower substrate having an upper surface situated on the lower surface of the upper substrate and stacked on the upper substrate in the downward direction, and a lower conductive layer provided between the lower surface of the upper substrate and the upper surface of the lower substrate and facing the upper conductive layer across the upper substrate. The upper surface of the transparent plate has a dome shape projecting upward on a cross section in a first direction perpendicular to the downward direction and on a cross section in a second direction perpendicular to the downward direction and the first direction. The lower surface of the transparent plate is concave upward on the cross section in the first direction is straight on the cross section in the second direction. The touch panel can be easily manufactured and reliably operated.

1. A touch panel comprising:
a transparent plate having an upper surface and a lower surface; an upper substrate having a lower surface and an upper surface which is situated on the lower surface of the transparent plate, the upper substrate being stacked on the transparent plate in a downward direction; an upper conductive layer provided between the lower surface of the transparent plate and the lower surface of the upper substrate; a lower substrate having an upper surface situated on the lower surface of the upper substrate, the lower substrate being stacked on the upper substrate in the downward direction; and a lower conductive layer provided between the lower surface of the upper substrate and the upper surface of the lower substrate, the lower conductive layer facing the upper conductive layer across the upper substrate, wherein the upper surface of the transparent plate has a dome shape projecting upward on a cross section in a first direction perpendicular to the downward direction and on a cross section in a second direction perpendicular to the downward direction and the first direction, and wherein the lower surface of the transparent plate is concave upward on the cross section in the first direction and is straight on the cross section in the second direction.
