## Abstract

An electronic device includes case and touch display module. The case has assembling groove, groove jointed surface and groove side surface. The touch display module disposed on the case has touch panel, adhesive element and positioning element. The touch panel located at the assembling groove has panel jointed surface and panel side surface. The panel jointed surface faces the groove jointed surface. The panel side surface faces the groove side surface. The adhesive element has two surfaces opposite to each other. The positioning element has auxiliary section and extended section. The auxiliary section is attached to one of the adhesive surface. The extended section extends from the adhesive surface and can be detachably clamped between the panel side surface and the groove side surface, which makes the gap between the groove side surface and the panel side surface is the same as the thickness of the extended section.
