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

A light-emitting device, comprising:

• a substrate;
• a cathode on the substrate;
• an anode facing the cathode;
• an interlayer comprising an emission layer, wherein the interlayer is located between the cathode and the anode;
• and
• a thermal acid generator,
• wherein the interlayer further comprises an electron transport region located between the cathode and the emission layer, wherein the electron transport region comprises a buffer layer, a hole blocking layer, an electron control layer, an electron transport layer, an electron injection layer, or a combination thereof, and
• wherein the electron transport region comprises the thermal acid generator,
• wherein the electron transport region comprises an electron transport layer and an electron injection layer, and the electron transport layer comprises a metal oxide,
• wherein
• the electron transport layer comprises the thermal acid generator, the electron injection layer comprises the thermal acid generator, or a combination thereof;
• the electron transport region further comprises a thermal acid generating layer comprising the thermal acid generator, wherein the thermal acid generating layer is in direct contact with the electron transport layer;
• the electron transport region further comprises a thermal acid generating layer comprising the thermal acid generator, wherein the thermal acid generating layer is in direct contact with the electron injection layer;
• or
• a combination thereof.
