A display device includes a first substrate, light emitting elements formed over the first substrate, a second substrate facing the first substrate, and a sealing member between the first and the second substrate to combine them. The sealing member is patterned to expose the light emitting elements. The sealing member may include black colored material to improve contrast, and dehydrating material may be part of the device to absorb moisture and/or oxygen. Accordingly, the transmittance of light generated from the light emitting elements increases and the luminance of display device improves.
