Broken glass on protect frame OLYMPUS XZ-2

Hello

My glass on protect frame OLYMPUS XZ-2 is broken. I think it is possible to change only the frame with protect glass or plastic (do not know exactly what kind of protect it is), becaouse on up side are two screws, Ithink only to unscrew and then change the damaged frame. The LCD is just OK no damage, touchscreen works OK. Only this protection looks bad. Do somebody have any idea where to get a frame or just to change the glass on frame. Best regards Ales
