Display device and method of manufacturing same

1. A method of manufacturing a display device, the method comprising:

providing a display substrate divided into a plurality of emission regions, and a non-emission region adjacent the emission regions, the display substrate comprising:

a base substrate;

organic light emitting devices at the emission regions, respectively; and

an encapsulation layer on the organic light emitting devices to seal the organic light emitting devices;

forming a black matrix on an upper surface of the encapsulation layer, the black matrix corresponding to the non-emission region; and

forming a plurality of color patterns on the upper surface of the encapsulation layer through a solution process, the plurality of color patterns corresponding to the emission regions,

wherein the encapsulation layer is located between the organic light emitting devices and the color patterns in a cross-sectional view, and

wherein the black matrix is formed after forming the encapsulation layer.

2. The method of claim 1 , wherein the solution process comprises an ink-jet process.

3. The method of claim 2 , wherein the forming the black matrix comprises performing a photolithography process.

4. The method of claim 3 , wherein the forming the black matrix comprises:

coating the display substrate with a photosensitive material to form a photosensitive layer;

selectively irradiating the photosensitive layer by using a mask;

baking the photosensitive layer; and

developing the photosensitive layer.

5. The method of claim 3 , wherein the forming the black matrix further comprises providing plasma on the display substrate to surface-treat the black matrix.

6. The method of claim 1 , wherein the forming the color patterns comprises:

providing a color solution to respective ones of the emission regions to form a plurality of color solution layers; and

drying the color solution layers.

7. The method of claim 6 , further comprising drying the color solution layers using heat.

8. The method of claim 7 , wherein a temperature of the heat is about 150 degrees (° C.) or below.

9. The method of claim 7 , wherein each of the color patterns is thinner than a respective one of the color solution layers, and is thinner than an adjacent region of the black matrix.

10. The method of claim 6 , wherein adjacent ones of the color patterns have different colors.

11. The method of claim 1 , wherein the encapsulation layer comprises an inorganic material deposited on the organic light emitting devices.

12. The method of claim 11 , wherein the black matrix and the color patterns are directly on the encapsulation layer.
