An organic display device and a manufacturing method are disclosed. The organic display device comprises: an organic light-emitting layer (15) located between an anode layer (13) and a cathode layer (14), and the organic light-emitting layer (15) comprises a plurality of pore-walls (16) formed of an organic material and a plurality of pores (17) to be filled with an organic light-emitting material (18). By delimiting the space of an organic light-emitting layer (15) into a plurality of pores (17), with each pore (17) occupying a smaller area of a pixel, the method reduces the inkjet-printing area, and increases the process tolerance of an inkjet-printing process, and further the method makes the inkjet-printing technology less dependent on the pixel size, shape, and other design factors, and thus the freedom degree of position-alignment becomes greater.
