Abstract

A display device is disclosed. The display device includes a display panel, a frame positioned in the rear of the display panel, a substrate positioned between the frame and the display panel, extended in an up-down direction of the frame, and mounted on the frame, a light source mounted on the substrate, and a lens covering the light source and mounted on the substrate. The lens includes a first stopper protruding and extending from a lower surface of the lens, and a first leg extended from the first stopper toward a lower part of the lens. The substrate includes a hole into which the first leg is inserted.

First claim

What is claimed is:

1. A display device comprising:
a display panel;
a frame positioned in a rear of the display panel;
a substrate positioned between the frame and the display panel, extended in an up-down direction of the frame, and mounted on the frame;
a light source mounted on the substrate; and
a lens covering the light source and mounted on the substrate,
wherein the lens includes:
a first stopper protruding and extending from a lower surface of the lens; and
a first leg extended from the first stopper toward a lower part of the lens and inserted into a hole of the substrate to fix the lens,
wherein the first leg is fixed to the hole by an adhesive supplied to the hole,
wherein the lens further includes a second leg positioned adjacent to the first leg and fixed to a surface of the substrate by the adhesive,
wherein the first stopper is positioned between the first leg and the surface of the substrate,
wherein a length of the second leg is substantially equal to a length of the first stopper,
wherein the lens further includes a third leg and a fourth leg that respectively face the first leg and the second leg with respect to a center of a lower surface of the lens,
wherein the fourth leg includes a stopper,
wherein the first leg faces the third leg with respect to the center of the lower surface of the lens,
wherein the second leg faces the fourth leg with respect to the center of the lower surface of the lens, and
wherein the first leg, the second leg, the third leg, and the fourth leg entirely form a rectangle and are respectively positioned at corners of the rectangle.

2. The display device of claim 1 , wherein a diameter of the first stopper is greater than a diameter of the first leg.

3. The display device of claim 1 , wherein a diameter of the first stopper is greater than a diameter of the hole.

4. The display device of claim 1 , wherein the adhesive is formed around the first stopper.

5. The display device of claim 1 , wherein the adhesive supplied to the hole is formed around the second leg.

6. The display device of claim 1 , wherein the lens further includes:
a receiving groove formed at a center of the lens and accommodating the light source;
a first lower surface formed on a perimeter of the receiving groove; and
a second lower surface formed on a perimeter of the first lower surface, and
wherein the first lower surface and the second lower surface form a stepped portion.

7. The display device of claim 6 , wherein the first stopper and the first leg are formed on the second lower surface of the lens.
