Abstract: This disclosure provides devices, systems, and methods for reducing substrate warpage in a display device. In one aspect, the display device includes a device substrate and a cover substrate, where the device substrate includes one or more display elements and the cover substrate includes a device cavity extending partially through the cover substrate. At least one of the display elements may be sealed by a primary seal in contact with and between the cover substrate and the device substrate to define a device area. A dummy area outside of the device area may be defined between the primary seal and a secondary seal, where the secondary seal is also in contact with and between the cover substrate and the device substrate. The display device may further include a dummy cavity extending partially through the cover substrate in the dummy area.
