Abstract: A display apparatus includes a substrate including a component area including a transmission area, a main area outside the component area, and a bending area bent based on a bending axis, a buffer layer disposed on the substrate, a first semiconductor layer disposed on the buffer layer, and a first gate insulating layer overlapping the first semiconductor layer and including a 1-1st opening corresponding to the bending area, and a 1-1st through-hole exposing a portion of the first semiconductor layer. A first acute angle formed by an inner surface of the 1-1st opening with respect to an upper surface of the substrate is less than a first contact acute angle formed by an inner surface of the 1-1st through-hole with respect to the upper surface of the substrate.

Abstract: A display panel includes a substrate including a transmissive area, a transistor over the substrate and adjacent to the transmissive area, a light-emitting diode electrically connected to the transistor, a bottom metal layer disposed between the substrate and the transistor and overlapping the transistor, and a plurality of inorganic insulation layers between the bottom metal layer and the light-emitting diode. An opening penetrating at least one of the inorganic insulation layers overlaps the bottom metal layer and thereby, an electronic device with improved image quality of the display panel may be implemented by preventing light emitted from components from entering thin-film transistors.
