Abstract

A display device includes a first substrate, a light-emitting element, a light conversion layer, and a color filter layer. The light-emitting element is disposed on the first substrate. The light conversion layer is disposed on the light-emitting element. In addition, the color filter layer is overlapped the light-emitting element and the light conversion layer.

Claims (17)

1. A display device, comprising:

a first substrate;

a light-emitting diode disposed on the first substrate;

a light conversion layer disposed on the light-emitting diode;

a color filter layer disposed on the light-emitting diode and the light conversion layer, wherein a width of the color filter layer is greater than a width of the light conversion layer;

an insulating layer disposed on the first substrate and having a recess, wherein the light-emitting diode is disposed in the recess of the insulating layer;

a light-shielding layer disposed on the insulating layer and having a recess, wherein in a cross-sectional view of the display device, the recess of the light-shielding layer comprises a first width and a second width, the first width is closer to the first substrate than the second width and the first width of the recess of the light-shielding layer is different from the second width of the recess of the light-shielding layer; and

a second substrate opposite to the first substrate;

wherein the recess of the light-shielding layer is overlapped with the recess of the insulating layer,

wherein in the cross-sectional view of the display device, the recess of the insulating layer has a minimum width, the recess of the light-shielding layer has a minimum width, the minimum width of the recess of the light-shielding layer is the first width of the recess of the light-shielding layer, and the minimum width of the recess of the insulating layer is less than the minimum width of the recess of the light-shielding layer.

2. The display device of claim 1 , wherein the light conversion layer, the color filter layer overlaps with the recess of the insulating layer.

3. The display device of claim 2 , wherein the width of the light conversion layer is greater than the minimum width of the recess of the insulating layer.

4. The display device of claim 1 , wherein the light-shielding layer is disposed between the first substrate and the second substrate, wherein the color filter layer is disposed in the recess of the light-shielding layer.

5. The display device of claim 4 , the second width of the recess of the light-shielding layer is greater than the minimum width of the recess of the insulating layer.

6. The display device of claim 1 , wherein the display device comprises a light-shielding region and a non-light-shielding region adjacent to the light-shielding region, the color filter layer is disposed in the non-light-shielding region, and a transistor is disposed in the light-shielding region.

7. The display device of claim 1 , further comprising a conductive layer disposed on the insulating layer, wherein the light-emitting diode is disposed on the insulating layer and the conductive layer is electrically connected to an upper electrode of the light-emitting diode.

8. The display device of claim 1 , further comprising a thin film transistor electrically connected to the light-emitting diode.
