A display device and a method of manufacturing the display device. An auxiliary electrode may be connected to a counter electrode without damaging a light-emitting element because a laser is not used.

Display device and method of manufacturing the same

An ink for a display device, the ink includes: an organic material, wherein the organic material has a molecular weight greater than about 500 and less than about 1,000,000, and the organic material in the ink has a concentration and the molecular weight of the organic material satisfy:<−3.518*ln()+45.59,wherein y is the concentration of the organic material, and x is the molecular weight of the organic material.

Ink including an organic material, display device using the same, and method of manufacturing display device

An inkjet spraying method includes preparing a spraying unit including nozzles for spraying an organic material on a target substrate including first pixels which display a same color, spraying the organic material to each of first pixels of a (1+a&#xd7;n)th first-pixel row in the first pixels, and spraying the organic material to each of first pixels of a (2+a&#xd7;n)th first-pixel row in the first pixels, where a first nozzle in the nozzles sprays the organic material to a first reference pixel in the first pixels of the (1+a&#xd7;n)th first-pixel row, a second nozzle, which is different from the first nozzle, in the nozzles sprays the organic material to a second reference pixel in the first pixels of the (2+a&#xd7;n)th first-pixel row, and the second reference pixel is disposed in parallel with the first reference pixel in a column direction.

Inkjet spraying method improving film uniformity of an organic layer, inkjet spraying device to improve film uniformity of an organic layer and display panel manufacturing method using same

An ink for a display device, the ink includes: an organic material, wherein the organic material has a molecular weight greater than about 500 and less than about 1,000,000, and the organic material in the ink has a concentration and the molecular weight of the organic material satisfy:3.518*1()+45.59,wherein y is the concentration of the organic material, and x is the molecular weight of the organic material.

An organic light-emitting display device including a driving element including an active pattern and a gate electrode, an insulation layer covering the driving element, a first diode electrode disposed on the insulation layer and electrically connected to the driving element, a pixel-defining layer disposed on the insulation layer and including a side surface defining an opening overlapping at least a portion of the first diode electrode, an edge-compensation part including an organic material and disposed in a peripheral area of the opening, an organic light-emitting layer disposed on the first diode electrode and the edge-compensation part, and a second diode electrode disposed on the organic light-emitting layer, in which the edge-compensation part includes an inclined surface contacting the organic light-emitting layer, and a taper angle of the inclined surface of the edge-compensation part is less than a taper angle of the side surface of the pixel-defining layer.
