A spacer layer (28) is disposed below the illumination layer and includes an aperture (28a) in registry with the light transmissive portion of the actuation layer. A contact layer (30) is disposed below the spacer layer and includes a dome portion (30a) having a convex side projecting into the aperture (28a) in the spacer layer (28).
