ABSTRACT:
A manufacturing method of organic electroluminescence display device according to the present invention performs (1) a first step for forming a non-affinity region in a surface of an anode provided in each of pixels arranged on a glass substrate by exposing the glass substrate in a saturated vapor pressure of an organic solvent, (2) a second step for forming an affinity region in a central portion of the anode surface spaced from its edges by irradiating the central portion of the anode surface with ultraviolet light, and (3) a third step for forming polymer material layers which constitute an organic electroluminescent element in the each of the pixels in the affinity region by blowing off polymer material solutions onto the affinity region of the anode in the each of the pixels, in this order, to simplify entire steps in, to reduce cost for, and to improve productivity of the manufacturing process of the organic electroluminescence display device thereby.
