Abstract
The present application discloses an OLED with an improved structure, comprising a reflective anode layer, a transparent cathode layer, an organic light-emitting layer sandwiched between the anode layer and the cathode layer, and a side reflective layer surrounding the organic light-emitting layer and forming a light exiting area together with the anode layer, wherein the light emitted from the light-emitting layer is reflected by both of the anode layer and the side reflective layer, and then leaves from the light exiting area. According to the present disclosure, the lateral light is reflected by the side reflective layer arranged around the organic light-emitting layer, such that the luminescent efficiency of the OLED with said improved structure can be significantly increased.
