Abstract: An organic light emitting display apparatus includes a substrate including a first display area having emission areas and transmissive areas, and a second display area adjacent to the first display area. The organic light emitting display further includes a plurality of sub-pixels disposed in the first display area, and a plurality of transistors electrically connected to the plurality of sub-pixels. The plurality of sub-pixels include a plurality of first sub-pixels disposed in the emission areas of the first display area and having a structure in which a plurality of light emitting stacks configured to emit light of different colors are stacked.

Abstract: A display device includes a substrate including an active area, a hole area disposed within the active area and having a through hole disposed therein, and a disconnection area surrounding the hole area; and a plurality of disconnection structures disposed on the substrate in the disconnection area, wherein each of the plurality of disconnection structures includes, a lower layer, an intermediate layer disposed on the lower layer and having a width smaller than that of the lower layer, and an upper layer disposed on the intermediate layer and having a width greater than that of the intermediate layer, thereby penetration of moisture or oxygen from the through hole into the active area is minimized.

Abstract: A plasma display panel and a plasma display apparatus are disclosed. The plasma display panel includes a front substrate including a scan electrode and a sustain electrode positioned parallel to each other, an upper dielectric layer positioned on the scan and sustain electrodes, a rear substrate on which an address electrode is positioned to intersect the scan and sustain electrodes, a lower dielectric layer positioned on the address electrode, a barrier rib positioned between the front substrate and the rear substrate to partition a discharge cell, and a phosphor layer positioned inside the discharge cell. The upper dielectric layer includes a glass-based material and a blue pigment. The phosphor layer includes a phosphor material and MgO material.
