Abstract: An organic light emitting display device includes scan lines arranged in horizontal lines, data lines intersecting the scan lines, a pixel array including pixels coupled to the scan lines and the data lines, the pixels including at least first color pixels, a panel tester including switching elements coupled to first ends of the data lines, the switching elements including at least first and second switching elements, and a first line coupled to the first switching elements and a second line coupled to the second switching elements. Data lines of K-th to (K+L)-th (where K and L are natural numbers) first color pixels arranged in a predetermined horizontal line are coupled to the first line through the first switching elements, and data lines of at least a part of remaining first color pixels arranged in the predetermined horizontal line are coupled to the second line through the second switching elements.

Abstract: A display device comprises a substrate, a first electrode on the substrate and extending in a first direction, a second electrode on the substrate and extending in the first direction, the second electrode being spaced apart from the first electrode in a second direction, a first insulating layer on the first electrode and the second electrode, light-emitting elements on the first insulating layer, the light-emitting elements being disposed on the first electrode and the second electrode, a second insulating layer disposed on the light-emitting elements, a first contact electrode disposed on the first electrode and electrically contacting the light-emitting elements, and a second contact electrode disposed on the second electrode and electrically contacting the light-emitting elements. The second insulating layer comprises patterns that cover at least part of the light-emitting elements and are spaced apart from one another in the first direction.
