Abstract: A display apparatus includes a display region and a peripheral region adjacent to the display region. The display apparatus further includes a first flexible substrate (FFS), a driving circuit (DC), a conductive pattern (CP), a conductive line, a light-emitting device, and a support substrate. The FFS includes a first surface and a second surface opposite the first surface. The second surface includes, in the peripheral region, a cavity extending into the FFS. The DC is on the first surface and includes at least one transistor. The CP is in the cavity and is partially exposed by the cavity. The conductive line electrically connects the CP to the DC. The light-emitting device is in the display region and is electrically connected to the DC. The support substrate is on the second surface. In a view normal to the second surface, the support substrate is spaced apart from the CP.
