Abstract
A manufacturing method of a bottom chassis includes providing a base plate having a flexibility and a first rigidity through a press molding process, providing a bent-maintaining member having a second rigidity greater than the first rigidity and being curved in a first direction through an extrusion molding process, and coupling the base plate to the bent-maintaining member.
Claims21
A bottom chassis comprising:
- a base plate which has a flexibility and a first rigidity, includes a sidewall unitary therewith and extending substantially perpendicular thereto, and is curved along a first direction;
- and
- a bent-maintaining member which comprises a plurality of chassis bars which has a second rigidity greater than the first rigidity, is curved along the first direction and coupled to the base plate, and maintains a curved shape of the base plate,
- wherein each of the plurality of chassis bars is coupled to an adjacent chassis bar thereto, and
- wherein at least one of the plurality of chassis bars is directly coupled to the sidewall of the base plate by a fixing member disposed in holes defined in the at least one of the plurality of chassis bars and the sidewall of the base plate.

- and
- a first and a second side walls respectively extending upward from the third and fourth sides,
- wherein each of the first and the second bent-maintaining members comprises,
- a plurality of chassis bars connected to the first and the second sides to be arranged along the first and the second sides;
- a first side chassis bar disposed on one side of each of the first and the second bent-maintaining members to be directly connected with the first side wall by a fixing member disposed in holes defined in the first side chassis bar and the first side wall of the base plate;
- and
- a second side chassis bar disposed on the other side of each of the first and the second bent-maintaining members to be directly connected with the second side wall by a fixing member disposed in holes defined in the second side chassis bar and the second side wall of the base plate.
