Abstract
Official abstract text for this publication.
A display device including: a substrate; a display element layer disposed on the substrate; a dam disposed around the display element layer; a plurality of patterns disposed between the dam and the display element layer, and a planarization layer disposed on the display element layer and the patterns, wherein the patterns have a hydrophile-lipophile balance value different from a hydrophile-lipophile balance value of the planarization layer.
First claim
Opening claim text (preview).
What is claimed is: 1. A display device, comprising: a substrate; a display element layer disposed on the substrate; a dam disposed around the display element layer; a plurality of patterns disposed between the dam and the display element layer; and a planarization layer disposed on the display element layer and the patterns, wherein the patterns have a hydrophile-lipophile balance value different from a hydrophile-lipophile balance value of the planarization layer. 2. The display device of claim 1 , further comprising: a first encapsulation layer disposed on the display element layer; and a second encapsulation layer disposed on the first encapsulation layer, wherein the planarization layer is disposed between the first encapsulation layer and the second encapsulation layer. 3. The display device of claim 2 , wherein the first encapsulation layer and the second encapsulation layer are disposed on the dam, and the patterns are spaced apart from each other on the first encapsulation layer. 4. The display device of claim 3 , wherein the planarization layer is spaced apart from the dam. 5. The display device of claim 4 , wherein a number of the patterns on which the planarization layer is disposed is equal to or smaller than about 60% of a total number of the patterns. 6. The display device of claim 1 , wherein the patterns have a lipophilicity, and the planarization layer has a hydrophilicity. 7. The display device of claim 6 , wherein the hydrophile-lipophile balance value of the planarization layer is within a range from about 15 to about 20. 8. The display device of claim 6 , wherein the hydrophile-lipophile balance value of the patterns is within a range from about 0 to about 5. 9. The display device of claim 1 , wherein the patterns have a hydrophilicity, and the planarization layer has a lipophilicity. 10. The display device of claim 1 , wherein the patterns are disposed in a matrix form. 11. The display device of claim 1 , wherein the patterns comprise: first patterns disposed adjacent to the display element layer; and second patterns disposed adjacent to the dam, and the first patterns and the second patterns are arranged staggered with respect to one another.
