Abstract
A display device includes a first substrate, a second substrate, a display layer, a bump, and a sealing material. The second substrate is disposed over the first substrate. The display layer is disposed between the first substrate and the second substrate, and has a boundary. The bump is connected to the first substrate or the second substrate and protrudes in a direction toward the opposite second substrate or first substrate, and is disposed around the boundary. The sealing material is filled between the bump and the display layer. The water vapor transmission rate of the bump is less than the water vapor transmission rate of the sealing material.
