ORGANIC ELECTROLUMINISCENT DISPLAY AND METHOD FOR PREPARING THE SAME, AND DISPLAY DEVICE

摘要

Disclosed are an organic electroluminescent display and a method for preparing the same, and a display device. The organic electroluminescent display comprises: a base substrate; an organic electroluminescent pixel array, which is set on the base substrate; a packaging coverplate or a packaging film, which is covered outside the organic electroluminescent pixel array; and a phase difference film and a polarization functional film located inside the packaging coverplate or the packaging film and attached to the organic electroluminescent pixel array in turn. In the organic electroluminescent display according to the invention, the unnecessary films, such as a TAC films that need to be attached to the two sides of a polarization functional film in an existing circular sheet polarizer and a binding agent layer, etc., can be omitted, thereby the transmittance of a display can be improved, and the contrast of a display can be increased; moreover, the overall thickness of a display may be reduced, and the problem of being difficult to roll up may be avoided; and there exists no interference of oxygen and aqueous vapor, thus the durability of the circular sheet polarizer can be increased.
