A display apparatus includes first and second substrates, a first side sealing layer, a ground connecting part, a flexible film, a driving circuit substrate, and a backlight assembly. The first substrate includes sides extending in a first and a second direction. The second substrate is disposed opposite to the first substrate and is larger in the second direction. The second substrate includes a thin film transistor, a ground wiring and first to fourth side surfaces. The first side sealing layer is disposed on the fourth side surface. The ground connecting part is disposed on the second substrate and is electrically connected to the ground wiring and the first side sealing layer. The flexible film is connected to the second substrate. The driving circuit substrate is connected to the flexible film. The backlight assembly is disposed between the driving circuit substrate and the first substrate.
