Light emitting device and display apparatus including same

Disclosed are a light emitting device and a display apparatus including the same. The light emitting device includes a first electrode, a hole transport region at (e.g., on) the first electrode, a light emitting layer at (e.g., on) the hole transport region, an electron transport region at (e.g., on) the light emitting layer, and a second electrode at (e.g., on) the electron transport region. The electron transport region includes a mixed layer in which a first compound represented by Formula 1 and a second compound different from the first compound and represented by Formula 2 are mixed. The hybrid layer is configured such that luminous efficiency and device lifetime of the light emitting device may be enhanced or improved. 公开了一种发光器件和包括该发光器件的显示装置。该发光器件包括第一电极、位于第一电极处(例如，上)的空穴传输区域、位于空穴传输区域处(例如，上)的发光层、位于发光层处(例如，上)的电子传输区域和位于电子传输区域处(例如，上)的第二电极。电子传输区域包括其中混合有由式1表示的第一化合物以及与第一化合物不同并且由式2表示的第二化合物的混合层。混合层被构造为使得可以增强或改善发光器件的发光效率和器件寿命。
