Abstract: An organic light emitting display device includes a light emitting layer for emitting light and for displaying an image, a fingerprint sensor for detecting a fingerprint, and a circuit element layer disposed between the light emitting layer and the fingerprint sensor and configured to control the light emitting layer. The fingerprint sensor includes a light receiver. The light receiver overlaps the light emitting layer and has an uneven surface.
