a display panel which receives the light from the light source and displays images.
2. The display device of claim 1 , wherein the circuit board is positioned perpendicular to the bottom plate of the container.
3. The display device of claim 2 , further comprising a board holding part disposed in the container and holds the circuit board.
4. The display device of claim 1 , wherein the fixing part further comprises a housing having a space therein and a conductive first terminal, the conductive first terminal disposed in the space of the housing.
5. The display device of claim 4 , wherein the circuit board further comprises a protruding edge and a contact terminal formed on the protruding edge of the circuit board, and
wherein the protruding edge is inserted into the space of the housing for the conductive first terminal to be connected with the contact terminal.
6. The display device of claim 5 , wherein the fixing part comprises a contact portion recessed to be electrically connected to the contact terminal of the circuit board.
7. The display device of claim 1 , wherein the socket part comprises a pair of branches, and
wherein middle portions of the branches are bent to each other to form a holding portion and a guiding portion, the holding portion holds the light source, and the guiding portion guides the light source toward the holding portion.
8. The display device of claim 7 , wherein a distance between the branches of the guiding portion is wider than a distance between the branches of the holding portion.
9. The display device of claim 7 , the light source comprising an electrode which is inserted into the holding portion via the guiding portion, wherein the electrode of the light source is a lead wire.
10. The display device of claim 1 , wherein the socket terminal is entirely conductive.
11. The display device of claim 1 , wherein the socket terminal is directly connected to the light source and the circuit board.
12. The display device of claim 1 , wherein the fixing part and the socket part are integrally formed.
13. A display device comprising:
a container comprising a bottom plate;
