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 pixel including: a light emitting element; a first transistor connected between a first node and a second node, and to generate a driving current to flow from a first power line to a second power line through the light emitting element; a second transistor connected between a data line and the first node; a third transistor connected between the second node and a third node corresponding to a gate electrode of the first transistor; a fourth transistor connected between the third node and a third power line; a fifth transistor connected between the first power line and the first node; a sixth transistor connected between the second node and a fourth node corresponding to a first electrode of the light emitting element; a seventh transistor connected between the fourth node and a fourth power line; and an eighth transistor connected between the fourth node and a fifth power line.
