Heat sink and display panel including heat sink

A display panel including a heat sink, the heat sink comprising:

• a first surface arranged to match and contact at least one semiconductor device;
• a second surface having a fin structure and adapted to dissipate heat from the heat sink into the air, the second surface arranged opposite to the first surface;
• combining portions having combining holes and adapted to be applied to a predetermined combining element to affix the at least one semiconductor device to the heat sink, the combining holes formed through the first surface and the second surface;
• and
• at least one protrusion arranged on the first surface adjacent to a periphery of an upper portion of the at least one semiconductor device;
• wherein the protrusion stops the at least one semiconductor device from rotating upon the at least one semiconductor device being affixed to the first surface of the heat sink by the combining element;
• and
• the at least one protrusion includes a bent portion accommodating a portion of the upper portion of the at least one semiconductor device.
