Display device
Disclosed is a display device. The display device includes: a light source; an optical sheet into which light is incident from the light source; a display panel disposed on the optical sheet and including an effective display region and a non-effective display region around the effective display region; and a light conversion/light-blocking sheet corresponding to the non-effective display region.
1. A display device comprising:
a light source;
an optical sheet into which light is incident from the light source;
a display panel disposed on the optical sheet and including an effective display region and a non-effective display region around the effective display region; and
a light conversion/light-blocking sheet corresponding to the non-effective display region,
wherein the optical sheet includes a light conversion sheet,
wherein the light conversion sheet includes:
a lower substrate;
an upper substrate on the lower substrate; and
a light conversion layer between the lower substrate and upper substrate,
wherein the light conversion/light-blocking sheet includes:
a light blocking part disposed between the display panel and the optical sheet; and
a light conversion part disposed on a lower surface of the light blocking part,
wherein the light blocking part includes a reflective surface directly facing the light conversion part.
2. The display device of claim 1 , wherein the light conversion part has a shape corresponding to a shape of the light blocking part.
3. The display device of claim 1 , wherein the light conversion part is directly disposed on a lower surface of the light blocking part.
4. The display device of claim 1 , wherein the reflective surface directly makes contact with the light conversion part.
5. The display device of claim 1 , wherein the light conversion layer includes a first host layer and a plurality of first light conversion particles including a semiconductor composition.
6. The display device of claim 5 , wherein the first light conversion particles include quantum dots.
7. The display device of claim 1 , wherein the light conversion part includes a second host layer and a plurality of second light conversion particles including a semiconductor composition.
8. The display device of claim 7 , wherein the second light conversion particles include quantum dots.
9. The display device of claim 1 , wherein the light conversion part includes a phosphor.
10. The display device of claim 9 , wherein the phosphor includes a yellow phosphor.
11. The display device of claim 9 , wherein the phosphor includes a green phosphor, a red phosphor, or a yellow phosphor.
12. The display device of claim 1 , wherein the light conversion/light-blocking sheet is disposed between the display panel and the optical sheet.
