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 includes a substrate, a circuit layer, a light emitting element layer, a sealing layer, and a polarization layer. A main area of the substrate includes a display area including emission areas and a non-display area disposed around the display area, the non-display area includes a dam area spaced apart from the display area, the dam area including at least one dam portion surrounding the display area. The non-display area also including a bonding area that surrounds the dam area, the circuit layer includes a buffer portion disposed in a part of the bonding area adjacent to the sub-area, the buffer portion being spaced apart from each of the sub-area and the dam area, and the polarization layer extends to the non-display area and overlaps the buffer portion.
