Abstract
To provide a display body device and a display apparatus that allow for improvement of an electrostatic withstanding voltage, a display body device 10E includes: a wiring substrate 30; a light-emitting element 12 and a drive IC 13 that are disposed on the wiring substrate 30; and a wiring pattern 36 that is disposed on an outermost side, and is at least partially exposed and has a potential equal to a ground of each of the light-emitting element 12 and the drive IC 13.
Claims11
A display body device, comprising:
- a wiring substrate having a first surface and a second surface opposed to the first surface, wherein
