Display device

1. A display device comprising:

a display panel displaying an image;

a light source unit supplying light to the display panel;

a light guide comprising:

an incidence plane facing the light source unit;

an emission plane facing the display panel; and

a light guide protrusion protruding in a direction perpendicular to a side of the light guide at an edge of the light guide;

a reflection sheet arranged opposite to the surface of the emission plane of the light guide, and including a reflection protrusion protruding in a direction perpendicular to a side of the reflection sheet at an edge of the reflection sheet and disposed so as to not overlap with the light guide protrusion; and

a supporting frame supporting an edge of the display panel, the light guide, and the reflection sheet, the supporting frame comprising:

a light guide protrusion receiving groove receiving the light guide protrusion of the light guide; and

a reflection protrusion receiving groove receiving the reflection protrusion of the reflection sheet.

2. The display device of claim 1 , wherein the light guide protrusion receiving groove and the reflection protrusion receiving groove are separated from each other according to a side of the supporting frame.

3. The display device of claim 1 , further comprising a flexible circuit board connected to one side of the display panel.

4. The display device of claim 3 , wherein the light source unit is integrally formed with the flexible circuit board.

5. The display device of claim 1 , further comprising optical sheets disposed between the light guide and the display panel, wherein the supporting frame supports an edge of the optical sheets.

6. The display device of claim 1 , further comprising an adhesive member attached to the supporting frame along with the reflection protrusion of the reflection sheet so as to fix the reflection protrusion of the reflection sheet inside the reflection protrusion receiving groove of the supporting frame.

7. The display device of claim 6 , further comprising a receiving member combined with the supporting frame so as to receive the light guide and the reflection sheet, wherein the adhesive member is attached to the edge of the supporting frame facing a bottom surface of the receiving member.
