A light-emitting device includes: a first electrode; a second electrode facing the first electrode; and an interlayer located between the first electrode and the second electrode and including an emission layer, wherein the interlayer includes a hole transport region located between the first electrode and the emission layer, the hole transport region includes a hole injection layer, the first electrode includes a conductive oxide and a first inorganic material, and the hole injection layer includes a second inorganic material. An electronic apparatus includes the light-emitting device.

Light-emitting device and electronic apparatus including the same

Provided are a light-emitting device and an electronic apparatus including the light-emitting device. The light-emitting device includes a first electrode, a second electrode facing the first electrode, and an interlayer disposed between the first electrode and the second electrode. The first electrode includes an oxide of: tungsten (W), molybdenum (Mo), copper (Cu), nickel (Ni), vanadium (V), or any combination thereof. The interlayer includes an emission layer and a layer including a tertiary amine compound including an organic selenium moiety, and the interlayer does not include a p-dopant.

An organic light-emitting device includes a condensed cyclic compound represented by Formula 1: The condensed cyclic compound has an electron withdrawing group (EWG) substituent and an electron donating group (EDG) substituent at suitable positions, and thus has a low ΔEand may be used as an effective thermally activated delayed fluorescence (TADF) light-emitting material.

Condensed cyclic compound and organic light emitting device comprising same

A light-emitting device includes a first electrode, a second electrode facing the first electrode, and an interlayer between the first electrode and the second electrode, the interlayer including an emission layer. The first electrode may be doped with a metal oxide having a work function of less than about −5.05 electron volts (eV), and a layer including a halide of a lanthanide may be between the first electrode and the emission layer. An electronic apparatus including the light-emitting device is also provided.

Light-emitting device and electronic apparatus comprising light-emitting device

A secondary battery includes: an electrode assembly; a case accommodating the electrode assembly; an electrode tab extending from the electrode assembly; a sealing part for insulating the electrode tab from the case; and an insulation film around the electrode tab and between the sealing part and the electrode assembly.
