Abstract:
1. A display apparatus, comprising: a display panel including a first substrate, a second substrate, and a touch sensor switch incorporated therein, the second substrate being opposed to the first substrate at an interval, the touch sensor switch being disposed in a display area that displays an image, wherein the touch sensor switch includes a first touch electrode provided on a surface of the first substrate, the surface being opposed to the second substrate, and a second touch electrode provided on a surface of the second substrate, the surface being opposed to the first substrate, the first touch electrode and the second touch electrode having an interval therebetween, wherein the touch sensor switch has a structure in which the first touch electrode and the second touch electrode are brought into contact with each other when the display panel is deformed by an external pressure, wherein the first substrate includes a convex portion that protrudes in a convex shape toward the second substrate, the convex portion being formed on the surface opposed to the second substrate, wherein the convex portion has a top surface opposed to the second substrate and includes a flat area formed on the top surface along the surface of the second substrate, wherein the first touch electrode is formed in the flat area on the convex portion as an isolated pattern, wherein the convex portion is formed in a forward tapered shape, and wherein the flat area is arranged to be inward of a tapered area of the convex portion and to have a length less than that of the top surface such that a first distance is equal to or larger than a second distance, in which the first distance is equal to a length between an end portion of the flat area and an inflection point whereat the top surface of the convex portion is curved to a side surface thereof that is inclined and in which the second distance is equal to a length between the inflection point and an end portion of the side surface.
