Abstract
Discloses is an organic light emitting display device including a first substrate divided into a pixel region and a non-pixel region. An organic light emitting element includes a first electrode, an organic thin film layer and a second electrode formed in the pixel region. A scan driver and a metal film corresponding to a region of the scan driver are formed in the non-pixel region. A second substrate is spaced apart from the pixel region and the non-pixel region of the first substrate. A frit is formed along an edge of a non-pixel region of the second substrate, wherein the frit is formed so that it can be overlapped with an active area of the scan driver formed in the non-pixel region.
