DISPLAY DEVICE

A display device is disclosed. The display device includes a first substrate, a light emitting unit on the first substrate, a second substrate sealing the light emitting unit, and a seal member attaching the first substrate to the second substrate. The light emitting unit includes a first electrode, an organic film layer having a light emitting layer, and a second electrode. At least one of layers constituting the light emitting layer includes a phosphorescence material. The seal member has an adhesive strength that lies substantially in a range between 5 and 200 kg f/cm2, a glass transition temperature that lies substantially in a range between 100 and 200° C., and a water vapor permeation rate greater than 0 and equal to or less than 10-2 g/m2/day.
