Abstract

An organic light emitting display device includes: a substrate including pixel areas and a pixel separating area; a plurality of pixels; a plurality of spacers in the pixel separating area and spaced apart from each other; and a touch electrode unit disposed over the plurality of pixels and spacers. The touch electrode unit includes first touch electrodes arranged in a first direction and second touch electrodes arranged in a second direction. The touch electrode unit includes a plurality of touch pattern unit blocks repeatedly arranged. Each touch pattern unit block includes portions of each of neighboring first touch electrodes and portions of each of neighboring second touch electrodes. The spacers of each touch pattern unit block corresponds to a plurality of spacer pattern unit blocks repeatedly arranged. Each spacer pattern unit includes at least one spacer and is smaller than the touch pattern unit block.
