Abstract

The invention provides a luminescent device and a display substrate, and belongs to the technical field of an organic light-emitting diode. The luminescent device and the display substrate can at least partially solve the problem that a current organic light-emitting diode display substrate with a resonant cavity has a smaller visual angle. The luminescent device includes an organic light-emittingdiode, wherein the organic light-emitting diode includes stacked cathode, luminescent layer and anode; and one side of the organic light-emitting diode is a reflection side being able to reflect light, and the other side of the organic light-emitting diode is a light emergent side. The luminescent device also includes a functional layer group which is arranged outside the light emergent side of the organic light-emitting diode, wherein the functional layer group is formed by a plurality of stacked functional layers; each functional layer is transparent; and any two adjacent functional layershave different refractive index.

Description

technical field [0001] The invention belongs to the technical field of organic light emitting diodes, and in particular relates to a light emitting device and a display substrate. Background technique [0002] Such as figure 1 As shown, in an organic light emitting diode (OLED) display substrate, each sub-pixel is provided with an organic light emitting diode 1 for emitting light. Since the display substrate generally only needs to emit light from one side, one side of the organic light emitting diode 1 can be set as the light emitting side with light reflection function (such as the cathode 12 itself of reflective material such as aluminum as a light reflection layer), for emitting light from the light emitting layer 22. The light is reflected to the light exit side (such as the side where the anode 13 of a transparent material such as indium tin oxide is located) and concentratedly emitted. [0003] The organic light emitting diode display substrate is affected by the re...
