Abstract
Disclosed is a display device in which a redundant light-emitting element is applicable to a micro light-emitting display device to which a high-resolution panel is applied. The display device includes at least one light-emitting element; and at least one redundant light-emitting element respectively disposed in a manner corresponding to the at least one light-emitting element, wherein a first electrode of the light-emitting element is connected to a second electrode of the redundant light-emitting element via a connection electrode. Thus, even when the light-emitting element is defective, light of a corresponding color thereto is emitted normally from the redundant light-emitting element. Thus, a failure of each pixel may be lowered.
Claims22
A display device comprising:
- a light-emitting element including a first electrode of a first type, a second electrode of a second type that is different from the first type and disposed opposite the first electrode, and a first light emitting layer between the first electrode of the first type and the second electrode of the second type;
- a redundant light-emitting element including a second electrode of the second type, a first electrode of the first type that is disposed opposite the second electrode of the second type of the redundant light-emitting element, and a second light emitting layer between the second electrode of the second type and the first electrode of the first type of the redundant light-emitting element;
- and
- a connection electrode connected to the first electrode of the first type of the light-emitting element and the second electrode of the second type of the redundant light-emitting element.
A display device comprising:
- a planarization layer having a first side and a second side that is opposite the first side;
- a first P-type electrode at the first side of the planarization layer;
- a first N-type electrode at the first side of the planarization layer;
- a first light emitting layer between the first P-type electrode and the first N-type electrode at the first side of the planarization layer;
- a second N-type electrode at the second side of the planarization layer;
- a second P-type electrode at the second side of the planarization layer;
- a second light emitting layer between the second N-type electrode and the second P-type electrode;
- and
- a connection electrode including a first end that is connected to the first P-type electrode at the first side of the planarization layer and a second end that is connected to the second N-type electrode at the second side of the planarization layer.
