Summary: | An electronic device including first to third light emitting regions and a dummy region is provided. The electronic device includes a base layer, and a display element layer including a pixel defining film on the base layer, light emitting elements divided by the pixel defining film, and a reduction preventing layer containing a reduction preventing agent, and the light emitting elements each include an electron transport region containing a metal oxide. The electronic device may have improved electron transport function of the electron transport region by the reduction preventing agent contained in the reduction preventing layer, thereby improving the luminous efficiency. |
