3. The receiving module of claim 2 , wherein the groove portion has a depth substantially equal to a thickness of the side wall, and the groove portion includes a fastening groove portion having an opposite shape of the fastening protrusion.
4. The receiving module of claim 3 , wherein the fastening protrusion has a shape of a triangular pyramid including two symmetric inclined planes.
5. The receiving module of claim 4 , wherein the mold frame includes a fastening groove portion in the form of a concave recess having a shape of a triangular pyramid including two symmetric inclined planes,
wherein:
the shape of the recess of the fastening groove portion is complementary to the shape of the fastening protrusion, and
the fastening protrusion is engageable with the recess to fix the mold frame to the at least one of the side walls.
6. The receiving module of claim 3 , wherein the fastening protrusion has a shape of a triangular wedge including a single inclined plane.
7. The receiving module of claim 6 , wherein the mold frame includes a fastening groove portion in the form of a concave recess having a shape of a triangular wedge including a single inclined plane,
wherein:
the shape of the recess of the fastening groove portion is complementary to the shape of the fastening protrusion, and
the fastening protrusion is engageable with the recess to fix the mold frame to the at least one of the side walls.
8. A liquid crystal display, comprising:
a liquid crystal display panel that displays an image;
a backlight unit at a rear side of the liquid crystal display panel;
a mold frame at an outer side of the liquid crystal display panel and the backlight unit;
a bottom chassis including a bottom portion facing the mold frame and the rear side of the backlight unit and including side walls connected with the bottom portion and facing an outer side of the mold frame;
wherein:
at least one of the side walls includes a fastening protrusion in at least one side thereof, and
the mold frame includes a groove portion that receives, at an outer side of the mold frame, the at least one side wall including the fastening protrusion such that the mold frame is combined to an inner side of the side wall and the fastening protrusion.
9. The LCD of claim 8 , wherein the fastening protrusion is formed throughout two sides of the at least one side wall along a height direction of the side wall.
10. The LCD of claim 9 , wherein the groove portion has a depth that is substantially equal to a thickness of the side wall, and the groove portion includes a fastening groove portion having an opposite shape of the fastening protrusion.
11. The LCD of claim 10 , wherein the fastening protrusion has a shape of a triangular pyramid having two symmetric inclined planes.
12. The LCD of claim 11 , wherein the mold frame includes a fastening groove portion in the form of a concave recess having a shape of a triangular pyramid including two symmetric inclined planes,
wherein:
the shape of the recess of the fastening groove portion is complementary to the shape of the fastening protrusion, and
the fastening protrusion is engageable with the recess to fix the mold frame to the at least one of the side walls.
13. The LCD of claim 10 , wherein the fastening protrusion has a shape of a triangular wedge having a single inclined plane.
14. The receiving module of claim 13 , wherein the mold frame includes a fastening groove portion in the form of a concave recess having a shape of a triangular wedge including a single inclined plane,
wherein:
the shape of the recess of the fastening groove portion is complementary to the shape of the fastening protrusion, and
the fastening protrusion is engageable with the recess to fix the mold frame to the at least one of the side walls.
15. The LCD of claim 8 , wherein the mold frame has a shape of a rectangular frame, and includes a receiving groove at an inner side thereof to support edges of the liquid crystal display panel.
