    Abstract: A display panel includes an emission area and a non-emission area. A light emitting element includes a first electrode, an emission layer on the first electrode, and a second electrode on the emission layer. A pixel defining layer includes a first opening defined therein and exposing the first electrode. A first encapsulation layer is on the second electrode to overlap the light emitting element. The first encapsulation layer includes a first inorganic layer on the second electrode and a second inorganic layer on the first inorganic layer. A top surface of the second electrode overlaps the first opening and includes at least one first stepped portion. A bottom surface of the second inorganic layer directly contacts a top surface of the first inorganic layer. At least one of the top surface of the first inorganic layer or a top surface of the second inorganic layer is a flat surface.

    IPC: H01L51/56 ,  H01L27/32

    Abstract: The method of manufacturing a display device includes preparing a substrate having a first and second area surrounding a portion of the first area, forming a semiconductor layer in the first area, forming a first insulating layer covering the semiconductor layer, forming a gate electrode layer that at least partially overlaps the semiconductor layer, forming a pad electrode layer in the second area, forming a second insulating layer covering the gate electrode layer, forming contact holes that at least partially expose the semiconductor layer and the gate electrode layer, and forming a conductive layer positioned in the contact holes and including a first and second layer. The forming of the conductive layer includes forming a first layer material and a second layer material, and removing a portion of the first layer material and a portion of the second layer material to expose the second insulating layer.

    IPC: B26F3/00 ,  B26D7/18

    Abstract: A cutting apparatus includes: a stage on which is disposed a preliminary stacked body from which a cut stacked body having an edge is formed; a cutting unit movable along a first direction corresponding to an extension direction of the edge of the cut stacked body and with which the preliminary stacked body is cut to form the cut stacked body; a first detaching unit movable in a direction forming an acute angle with the first direction and including a first detaching tool which contacts the cut stacked body in detaching of the cut stacked body from the carrier substrate; and a second detaching unit movable in a direction parallel to the first direction and including a second detaching tool which is inserted between the cut stacked body and the carrier substrate in the detaching of the cut stacked body from the carrier substrate.
