Organic light-emitting display device and method of manufacturing the same |
摘要 |
An organic light-emitting display device is provided. An organic light-emitting display device, including: a substrate; a pixel-defining layer on the substrate and defining a light-emitting region; and an organic light-emitting element over the light-emitting region, wherein the pixel-defining layer includes a first pixel-defining layer on the substrate and a second pixel-defining layer on the first pixel-defining layer, the organic light-emitting element includes a first organic layer contacting the first pixel-defining layer at either end thereof, a second organic layer on the first organic layer and contacting the second pixel-defining layer at either end thereof, and an organic light-emitting layer on the second organic layer, and the first pixel-defining layer is lyophilic. |

1. An organic light-emitting display device, comprising:
a substrate; a pixel-defining layer on the substrate and defining a light-emitting region; and an organic light-emitting element over the light-emitting region, wherein the pixel-defining layer comprises:
a first pixel-defining layer on the substrate; anda second pixel-defining layer on the first pixel-defining layer, wherein the organic light-emitting element comprises:
a first organic layer contacting the first pixel-defining layer at either end thereof;a second organic layer on the first organic layer and contacting the second pixel-defining layer at either end thereof; andan organic light-emitting layer on the second organic layer, wherein the first pixel-defining layer is lyophilic, and wherein a concentration of fluorine ions bonded onto a surface of the first pixel-defining layer differs from a concentration of fluorine ions bonded onto a surface of the second pixel-defining layer. |
