The invention provides a WOLED device. The WOLED device comprises a total reflection anode, a hole transport layer, an electron blocking layer, a red phosphorescent light emitting layer, a blue fluorescent light emitting layer, a green phosphorescent light emitting layer, a hole blocking layer, an electron transport layer and a semi-transparent cathode which are stacked from the bottom up in sequence, wherein the main body material of the red phosphorescent light emitting layer is a hole transport type main body material; the main body material of the blue fluorescent light emitting layer is a bipolar transport type main body material; and the main body material of the green phosphorescent light emitting layer is an electron transport type main body material. By virtue of the additional electron blocking layer and the hole blocking layer, and by adoption of the total reflection anode and the semi-transparent cathode, electron and hole utilization rate can be improved effectively; and in addition, by selecting the reasonable main body materials and energy level design, singlet state exciton and triplet state exciton generated by the blue fluorescent layer can be fully utilized, thereby greatly improving the luminous efficiency of the WOLED device.
