Abstract

According to one or more embodiments of the present invention, a display apparatus includes: a substrate; a display unit which is formed on the substrate and includes an emission area and a non-emission area; a first coating layer which is formed on the display unit and has an uneven area formed on the emission area; a first blocking layer which is formed on the non-emission area of the first coating layer; and a second blocking layer which is formed on the first blocking layer and prevents reflection of external light.

Claims (34)

1. A display apparatus comprising:

a substrate;

a display unit on the substrate, the display unit comprising an emission area and a non-emission area;

a first coating layer on the emission area and the non-emission area of the display unit, the first coating layer having an uneven area on the emission area;

a first blocking layer on the non-emission area; and

a second blocking layer on the first blocking layer, the second blocking layer configured to prevent reflection of external light,

wherein the display unit comprises an organic light-emitting device (OLED) comprising a first electrode, an intermediated layer, and a second electrode,

wherein the second blocking layer is disposed on the second electrode, and

wherein a surface of the first coating layer on the emission area is phobic to the first blocking layer and a surface of the first coating layer on the non-emission area is philic to the first blocking layer.

2. The display apparatus of claim 1 , wherein the first blocking layer comprises a black matrix.

3. The display apparatus of claim 1 , wherein the first coating layer comprises a waterborne binder.

4. The display apparatus of claim 1 , wherein the second blocking layer comprises one or more dielectric layers alternately stacked with one or more metal layers.

5. A display apparatus comprising:

a substrate;

a display unit on the substrate, the display unit comprising an emission area and a non-emission area;

a first coating layer on the display unit, the first coating layer having an uneven area on the emission area;

a first blocking layer on the non-emission area; and

a second blocking layer on the first blocking layer, the second blocking layer configured to prevent reflection of external light,

wherein the display unit comprises an organic light-emitting device (OLED) comprising a first electrode, an intermediated layer, and a second electrode,

wherein the second blocking layer is disposed on the second electrode, and

wherein the second blocking layer sequentially comprises a first dielectric layer, a first metal layer, and a second dielectric layer from an upper part of the display unit.

6. The display apparatus of claim 5 , wherein the second blocking layer further sequentially comprises a second metal layer and a third dielectric layer from an upper part of the second dielectric layer.

7. The display apparatus of claim 1 , wherein the display unit comprises a pixel-defining layer having an opening; and

wherein the emission area is formed by the opening.

8. The display apparatus of claim 1 , further comprising an encapsulation layer on the display unit.

9. The display apparatus of claim 1 , further comprising a second coating layer on the first coating layer, the second coating layer has a greater refractive index than the first coating layer.

10. A display apparatus comprising:

a substrate;

a display unit on the substrate, the display unit comprising an emission area and a non-emission area;

a first coating layer on the emission area and the non-emission area of the display unit, the first coating layer having an uneven area on the emission area;

a first blocking layer on the non-emission area; and

a second blocking layer on the first blocking layer, the second blocking layer configured to prevent reflection of external light,

wherein the second blocking layer is disposed over the emission area and the non-emission area of the display unit, and

wherein a surface of the first coating layer on the emission area is phobic to the first blocking layer and a surface of the first coating layer on the non-emission area is philic to the first blocking layer.
