Abstract
A display apparatus includes a display panel including a first substrate, a second substrate opposed to the first substrate, and a touch sensor switch disposed in a display area that displays an image. The touch sensor switch includes a first touch electrode provided on a surface of the first substrate and a second touch electrode provided on a surface of the second substrate. The touch sensor switch has a structure in which the first and second touch electrodes are brought into contact when the display panel is deformed by an external pressure. The first substrate includes a convex portion that protrudes in a convex shape toward the second substrate. The convex portion has a top surface opposed to the second substrate and includes a flat area formed on the top surface. The first touch electrode is formed in the flat area on the convex portion as an isolated pattern.
