• a cover window comprising:
• a front surface including a transmission area and a bezel area adjacent the transmission area;
• and a rear surface opposite to the front surface, the bezel area comprising an opening;
• a stiffener comprising:
• a support portion disposed on the rear surface;
• an insertion portion protruding from the support portion and inserted in the opening;
• a first bending portion extending from the support portion and bent from the support portion at a first angle;
• and a second bending portion extending from the first bending portion and bent from the first bending portion at a second angle;
• and
• a cover part disposed in the insertion portion and of which at least a portion is exposed through the opening at the front surface,
• wherein the first bending portion comprises:
• a first portion bent from the support portion;
• a second portion bent from the first portion;
• and an additional portion connected to at least one of the first portion and the second portion,
• wherein a moment of inertia i of the first bending portion equals bh3/12,
• where b is a thickness of the first bending portion in a thickness direction, and h is a height of the first bending portion in a height direction perpendicular to the thickness direction.
