Title
(EN) Display device and method for manufacturing the same
Abstract
(EN)

A display device including a first substrate and a pixel defining layer disposed on the first substrate. The pixel defining layer is configured to define an emissive area and a transmissive area. The display device also includes a first electrode disposed in the emissive area, a light emitting layer disposed on the first electrode, and a second electrode disposed in the emissive area and the transmissive area. The second electrode includes an oxide layer in the transmissive area.
