Abstract
A display device includes: a first substrate; a second substrate facing the first substrate; a light-amount adjusting layer interposed between the first substrate and the second substrate; and a backlight unit disposed under the first substrate, wherein the second substrate includes a plurality of color conversion layers respectively disposed on a plurality of pixel regions, the color conversion layer includes a partition wall; and a phosphor disposed on areas defined by the partition wall, and the color conversion layer includes an air layer between the second substrate and the phosphor.
Claims12
A display device comprising:
- a first substrate;
- a second substrate facing the first substrate;
- a plurality of color conversion layers disposed under the second substrate;
- and
- a light source disposed under the first substrate, the plurality of color conversion layers being interposed between the first substrate and the second substrate,
- wherein:
- the plurality of color conversion layers are respectively disposed on a plurality of pixel regions;
- the color conversion layer comprises:
- a plurality of partition walls;
- a phosphor disposed on areas defined by the partition walls;
- and
- an air layer located between adjacent ones of the partition walls and overlapping the pixel region, the pixel region configured to transmit a light of the light source;
- the phosphor is disposed between the air layer and the light source;
- each of the partition walls comprises a reflective surface facing the air layer;
- and
- a width of the air layer gradually decreases as the air layer is further away from the phosphor.
