Abstract:
A display structure is provided. The display structure includes: an array layer; a transparent anode layer disposed on the array layer; a light-emitting element layer disposed on the transparent anode layer; a light reflective layer disposed on the light-emitting element layer and sequentially including a reflective cathode layer, a cathode protection layer, and a reflective metal layer; and an encapsulation layer disposed on the light reflective layer. A reflective metal layer is added between the encapsulation layer and the reflective cathode layer, thereby increasing a light-emitting efficiency of a bottom-emission type organic light-emitting diode, further enhancing the moisture and oxygen block capability of the OLED device, and effectively improving the optical properties and the moisture and oxygen resistance of OLED display panels.
