Abstract

A light-emitting device includes: an anode disposed on a base, and a cathode disposed on a side of the anode facing away from the base. The anode includes a light-reflecting sub-electrode and a light-transmitting sub-electrode located on a surface of the light-reflecting sub-electrode facing away from the base, and an orthographic projection of the light-transmitting sub-electrode on the base is located within a range of an orthographic projection of the light-reflecting sub-electrode on the base. The light-reflecting sub-electrode includes a metal pattern and a metal oxide pattern, and the metal oxide pattern is located in at least part of a region around the metal pattern.
