Abstract

A display device including a display panel which displays images, an intermediate frame on which the display panel is seated, a lower receptacle which includes a first receiving portion including a bottom plate and sidewalls, and a second receiving portion separate from the first receiving portion, and a light source unit which includes an alignment plate and a point light source mounted on the alignment plate. The light source unit contacts the sidewalls of the lower receptacle, and the first receiving portion is coupled with the intermediate frame.

Claims

1. A display device comprising:

an upper receptacle;

a display panel which displays images;

an intermediate frame on which the display panel is seated;

a unitary indivisible lower receptacle which includes a sidewall and a first hole disposed in the sidewall; and

a light source unit which includes an alignment plate and a point light source disposed on the alignment plate,

wherein the light source unit is removably coupled with the lower receptacle.

2. The display device of claim 1, wherein the light source unit is removably coupled with the sidewall of the lower receptacle, the point light source disposed extending through the first hole in the sidewall.

3. The display device of claim 2, wherein the first hole is a single continuous member disposed extending parallel to a lengthwise direction of the sidewall.

4. The display device of claim 2, wherein

the alignment plate includes a first surface and a second surface opposing the first surface, and the sidewall of the lower receptacle includes an internal surface and an external surface,

the point light source being mounted on the first surface of the alignment plate, and the first surface of the alignment plate and the external surface of the sidewall contact each other.

5. The display device of claim 2, wherein the light source unit further includes a fastening portion coupled with the sidewall.

6. The display device of claim 5, wherein

the intermediate frame includes a first sidewall portion and a first cutting portion, the first sidewall portion facing the sidewall of the lower receptacle, and

the first cutting portion being disposed in the first sidewall and aligned with the fastening portion of the light source unit, the fastening portion being exposed to an outside of the display device through the first cutting portion.

7. The display device of claim 6, wherein

the upper receptacle includes a second sidewall portion and a second cutting portion, the second sidewall portion facing the first sidewall portion of the intermediate frame, and

the second cutting portion being disposed in the second sidewall portion to overlap with the first cutting portion, the fastening portion being exposed to the outside of the display device through the first cutting portion and the second cutting portion.

8. The display device of claim 1, wherein the lower receptacle further includes a bottom plate, the sidewalls extending from the bottom plate.

9. A display device comprising:

an upper receptacle;

a display panel which displays images;

an intermediate frame on which the display panel is seated;

a unitary indivisible lower receptacle which includes a bottom plate, a sidewall extending from the bottom plate, and a second hole disposed in the bottom plate; and

a light source unit which includes an alignment plate and a point light source mounted on a first surface of the alignment plate,

wherein the light source unit is removably coupled with the lower receptacle.

10. The display device of claim 9, wherein the second hole is a single continuous member extending parallel to a lengthwise direction of the sidewall.

11. The display device of claim 10, wherein

the second hole has a first width and a second width taken in a same direction parallel to the bottom plate of the lower receptacle, and

the first width of the second hole is equal to or greater than a thickness of the alignment plate, and the second width of the second hole is equal to or greater than a sum of the thickness of the alignment plate and a thickness of the point light source, the thicknesses taken perpendicular to the first surface of the alignment plate.

12. The display device of claim 11, wherein the alignment plate includes the first surface and a second surface opposing the first surface, and the sidewall includes an internal surface and an external surface, the second surface of the alignment plate and the internal surface of the sidewall contacting each other.

13. The display device of claim 9, wherein the sidewall further includes a fastening portion coupled with the light source unit.

14. The display device of claim 9, wherein

the sidewall of the lower receptacle further includes a first fastening portion, and the alignment plate of the light source unit includes a second fastening portion aligned with the first fastening portion;

and

a fixing member is engaged with the first and second fastening portions, such that the light source unit is removably coupled with the lower receptacle solely by the fixing member being engaged with the aligned first fastening portion and second fastening portion.

15. The display device of claim 13, wherein

the intermediate frame includes a first sidewall portion and a first cutting portion, the first sidewall portion facing the sidewall of the lower receptacle, and the first cutting portion being disposed in the first sidewall portion and aligned with the fastening portion, the fastening portion being exposed to an outside of the display device through the first cutting portion.

16. The display device of claim 15, wherein

the upper receptacle includes a second sidewall portion and a second cutting portion, the second sidewall portion facing the first sidewall portion of the intermediate frame, and

the second cutting portion being disposed in the second sidewall portion to overlap with the first cutting portion, the fastening portion being exposed to the outside of the display device through the first cutting portion and the second cutting portion.

17. The display device of claim 10, wherein the light source unit further includes a unitary indivisible support member on which the alignment plate is mounted, the support member being coupled directly with the lower receptacle.

18. The display device of claim 17, wherein the support member includes a support plate and a support wall extending from the support plate.

19. The display device of claim 18, wherein the support member is coupled directly with the bottom plate of the lower receptacle.
