Abstract: A sealing layer covers more surely both of a display region and a peripheral region on a substrate. A dummy structure is formed in the peripheral region of the substrate. The dummy structure contains, for instance, at least one of the materials constituting an organic EL display structure. The dummy structure is located in the peripheral region so that the volume per unit area of the sealing layer in the peripheral region is substantially the same as that in the display region.

Abstract: A light emitting display device and a driving method thereof are provided, in which a luminance difference occurring in a boundary between a fingerprint scanning area and a non-fingerprint scanning area is not perceived by a user. The light emitting display device can include a display panel including a display area where a plurality of pixels is provided to display an image. The display area can include a first area, a second area, and a boundary area disposed between the first area and the second area. In a case where the display panel displays a predetermined image pattern, each of pixels in the first area can emit a first light having a first luminance, each of pixels in the second area can emit a second light having a second luminance lower than the first luminance or cannot emit any light, and the luminance of pixels in the boundary area can be progressively reduced from the first area to the second area.
