Organic light emitting display and method of manufacturing the same
View Patent ↗An organic light emitting display includes a first substrate having a plurality of pixel areas, a driving transistor disposed on the first substrate, an organic layer disposed on the driving transistor, a first electrode disposed on the organic layer and electrically connected to the driving transistor, an insulating layer pattern disposed on the organic layer, the insulating layer pattern having a first opening corresponding to each pixel area, a bank pattern disposed on the insulating layer pattern, the bank pattern having a second opening corresponding to the first opening, an organic light emitting layer disposed in the first and second openings, and a second electrode disposed on the organic light emitting layer.
1. An organic light emitting display comprising:
a first substrate having a plurality of pixel areas;
a driving transistor disposed on the first substrate;
an organic layer disposed on the driving transistor;
a first electrode disposed on the organic layer and electrically connected to the driving transistor;
an insulating layer pattern disposed on the organic layer, the insulating layer pattern having a first opening corresponding to each pixel area;
a bank pattern disposed on the insulating layer pattern, the bank pattern having a second opening corresponding to the first opening;
an organic light emitting layer disposed in the first and second openings; and
a second electrode disposed on the organic light emitting layer,
wherein the first substrate comprises a bonding area surrounding the pixel areas, and a third opening is formed through the bank pattern corresponding to the bonding area.
2. The organic light emitting display of claim 1 , further comprising:
a second substrate facing the first substrate; and
a bonding member disposed between the first substrate and the second substrate to couple the first substrate to the second substrate.
3. The organic light emitting display of claim 2 , wherein the bonding member contacts the insulating layer pattern in the bonding area through the third opening.
4. The organic light emitting display of claim 3 , wherein the insulating layer pattern comprises silicon nitride.
5. The organic light emitting display of claim 1 , wherein the bank pattern comprises a photoresist material.
6. The organic light emitting display of claim 1 , wherein the organic layer is removed from the bonding area.
7. The organic light emitting display of claim 1 , wherein the insulating layer pattern prevents gas or moisture generated from the organic layer from penetrating into the organic light emitting layer.
