Abstract

The invention discloses a light emitting device, a manufacturing method thereof, a mask plate, a display substrate and a display device, and belongs to the technical field of display. The method comprises the steps of forming an auxiliary electrode and a first electrode on a substrate, wherein the first orthographic projection of the auxiliary electrode on the substrate is located outside the second orthographic projection of the first electrode on the substrate; depositing a light emitting layer on the substrate with the auxiliary electrode and the first electrode by using the mask plate witha hollowed-out area; and forming a second electrode on the substrate with the light emitting layer. The method solves a problem that impurity particles will affect the light emission of the light emitting layer, and enables the light emitting effect of the light emitting device not to be affected by the impurity particles. The method is applied to the display device.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display device, a manufacturing method thereof, a mask plate, a display substrate and a device. Background technique [0002] An organic light-emitting diode (English: Organic Light-Emitting Diode; abbreviation: OLED) display device has been widely used due to its better display effect. [0003] In the related art, an OLED display device includes: a light-emitting device, the light-emitting device includes: a base substrate, an insulating layer, an OLED, and an auxiliary electrode, and the OLED includes an anode, a light-emitting layer, and a cathode arranged in sequence along a direction away from the base substrate. Both the auxiliary electrode and the insulating layer are located between the base substrate and the light-emitting layer of the OLED, and are sequentially arranged along a direction away from the base substrate. Moreover, the cathode of the OLED is el...
