Abstract

A display panel includes a first substrate, a second substrate, at least one light-emitting diode, at least one reflective layer, and at least one first spacer layer. The first substrate has a filter layer. The second substrate is opposite to the first substrate. The light-emitting diode is disposed on the second substrate. The reflective layer is located on the first substrate and protrudes toward the second substrate. The first spacer layer is located between the first substrate and the second substrate. The first spacer layer has a first end and a second end, and the first end of the first spacer layer is located between a surface of the reflective layer adjacent to the second substrate and the second substrate.

Claims (22)

1. A display panel, comprising:

a first substrate having a filter layer;

a second substrate opposite to the first substrate;

at least one light-emitting diode disposed on the second substrate;

at least one reflective layer located on the first substrate and protruding toward the second substrate, wherein a material of the reflective layer comprises metal, the reflective layer has a first section, a second section, and a third section connected with the first section and the second section, the second section is located between the first spacer layer and the first substrate, the third section is in contact with a sidewall of the first spacer layer, and the first end of the first spacer layer covers the first section; and

at least one first spacer layer located between the first substrate and the second substrate, the first spacer layer has a first end and a second end, wherein the first end of the first spacer layer is located between a surface of the reflective layer adjacent to the second substrate and the second substrate.

2. The display panel of claim 1 , wherein an edge of the first end of the first spacer layer is substantially aligned with an edge of the reflective layer adjacent to the first end along a direction perpendicular to the first substrate.

3. The display panel of claim 1 , wherein an edge of the second end of the first spacer layer is substantially aligned with an edge of the reflective layer adjacent to the second end along a direction perpendicular to the first substrate.

4. The display panel of claim 1 , further comprising:

a second spacer layer located on the first substrate and protruding toward the second substrate, the third section of the reflective layer is in contact with a sidewall of the second spacer layer, and the first section of the reflective layer is located between the first spacer layer and the second spacer layer.

5. The display panel of claim 1 , wherein the first substrate further comprises:

a protection film covering the filter layer, wherein a material of the protection film comprises transparent conductive layer.

6. The display panel of claim 1 , wherein the first substrate further comprises:

a black matrix, wherein a projection of the reflective layer on the first substrate is within a projection of the black matrix on the first substrate.

7. The display panel of claim 1 , further comprising:

a color conversion layer located between the filter layer and the light-emitting diode.

8. The display panel of claim 1 , wherein the light-emitting diode and the filter layer have the same color.

9. The display panel of claim 1 , further comprising a plurality of color regions, wherein when viewed from a direction along the arrangement of the color regions, a number of the at least one first spacer layer is plural, a number of the at least one reflective layer is plural, and adjacent two of the first spacer layers are located between adjacent two of the reflective layers.

10. The display panel of claim 9 , wherein a color conversion layer is located between the two first spacer layer.

11. The display panel of claim 1 , wherein the first spacer layer comprises a light-absorbing photoresist material.

12. The display panel of claim 1 , further comprising a plurality of light-emitting diodes respectively correspond to a first color region, a second color region, and a third color region, and wherein the first color region further comprises:

a color conversion layer located between the first substrate and the second substrate, and the color conversion layer is overlapped with the filter layer along a direction substantially perpendicular to the first substrate.
