A display device includes a substrate; a light-emitting element on the substrate; a capping layer on the light-emitting element; a first inorganic encapsulation layer on the capping layer; an organic encapsulation layer on the first inorganic encapsulation layer; and a second inorganic encapsulation layer on the organic encapsulation layer. The first inorganic encapsulation layer includes a first sub-inorganic encapsulation layer between the capping layer and the organic encapsulation layer, and a second sub-inorganic encapsulation layer between the first sub-inorganic encapsulation layer and the organic encapsulation layer.

Display device with a plurality of inorganic encapsulation layers

A display device includes: a substrate on which a display area and a non-display area are defined; a plurality of pixels disposed on the substrate in the display area; and an encapsulation layer disposed on the pixels to cover the pixels, where the encapsulation layer including a first region and a second region different from the first region. The encapsulation layers has a thickness in a range of 1.75 &#x3bc;m to 4.0 &#x3bc;m, and the ratio of a thickness of the second region of the encapsulation layer to a thickness of the first region of the encapsulation layer is in a range of 0.95 to 1.0.

Display device having encapsulation layer

A light-emitting diode according to an exemplary embodiment includes: a first electrode; a second electrode overlapping the first electrode; an emission layer positioned between the first electrode and the second electrode; and a first capping layer positioned on the first electrode, wherein the first capping layer includes at least one among LiF, MgF, AlF, NaF, and AlO, and a thickness of the first capping layer is 30 nm to 40 nm.

Light emitting diode

An organic light-emitting diode (OLED) display is disclosed. In one aspect, the display includes a substrate including a display area configured to display an image and a non-display area surrounding the display area. A plurality of OLEDs are positioned in the display area, each of the OLEDs including first and second electrodes spaced apart from each other. A plurality of pixel circuits are positioned in the display area, each of the pixel circuits including a plurality of thin film transistors (TFTs) and a node line electrically connected to at least two of the TFTs and at least partially overlapping the corresponding first electrode in the depth dimension of the OLED display so as to form a parasitic capacitor. The parasitic capacitor includes a first parasitic capacitor and a second parasitic capacitor, the first parasitic capacitor having a larger capacitance than that of the second parasitic capacitor.
