Abstract: The present disclosure relates to a display apparatus. The display apparatus may include a display panel, a peripheral region, an electronic component, and a gap-fill layer. The display panel defines a display region. The peripheral region is adjacent to the display region. The peripheral region includes lines and pads. The lines are disposed in the peripheral region, and the pads are connected to the lines. The electronic component includes connecting pads in contact with the pads. The gap-fill layer is between the display panel and the electronic component, between the connection pads, between the pads, and in the openings. Each of the pads may overlap at least two pads of the connection pads, and the openings may overlap between the connection pads, when viewed in a plan view.
