Abstract
An organic light-emitting display device includes: a plurality of pixels arranged in a matrix, wherein each of the pixels includes: an organic light emitting element; a first transistor including a gate electrode coupled to a scan line, a first electrode coupled to a data line, and a second electrode coupled to a first node, a second transistor configured to drive the organic light emitting element according to a data voltage provided through the first transistor; a third transistor including a first electrode coupled to the first node and a second electrode coupled to a second node; a first capacitor between the first node and a third node configured to have an initialization voltage applied; and a second capacitor between a fourth node coupled to a gate electrode of the second transistor and the second node.
