Display device

A display device comprising:

• a display panel comprising first pads and second pads;
• a first connection circuit board electrically connected to the first pads;
• and
• a second connection circuit board electrically connected to the second pads,
• wherein the first connection circuit board comprises:
• a first connection part electrically connected to the first pads, the first connection part being located at a first end of the first connection circuit board;
• and
• a first pattern part defining at least two first protrusion parts that are spaced apart along a first direction, the at least two first protrusion parts defining at least two free ends protruding away from the first end of the first connection circuit board along a second direction crossing the first direction, the at least two free ends comprising first input pads to be electrically connected to a main circuit board,
• wherein the second connection circuit board comprises:
• a second connection part electrically connected to the second pads;
• and
• a second pattern part protruding along the second direction, and defining at least one second protrusion part that does not overlap with the first protrusion parts when viewed on a plane that is parallel to a surface of the display panel, the at least one second protrusion part comprising second input pads to be electrically connected to the main circuit board between the first input pads of the at least two free ends,
• wherein the first protrusion parts have a symmetrical shape relative to a first reference line extending through a center of the first connection circuit board in a direction perpendicular to the first direction, and
• wherein the second protrusion part has a symmetrical shape relative to a second reference line extending through a center of the second connection circuit board in a direction perpendicular to the first direction.
