Problems solved by technology

Among them, the sputtering process is usually used to prepare the cathode covering the entire layer of the display area. However, when preparing the cathode in the prior art, the cathode formed by sputtering often exceeds the display area. On the one hand, short circuits are prone to occur, which reduces the yield of OLED devices; On the one hand, the frame of the OLED device will become larger, which is not conducive to the realization of a narrow frame of the OLED device

Abstract

The invention, which belongs to the technical field of display, provides a display substrate and a manufacturing method thereof, and a display device. The manufacturing method comprises the followingsteps that: a deformable film layer covering a non-display area of a display substrate is formed, wherein the deformable film layer includes a hollow-out part corresponding to a display area of the display substrate; an overall electrode layer is formed on the display substrate with the deformable film layer formed; the size of the deformable film layer is increased and thus the electrode layer part formed on the deformable film layer is separated from the electrode layer part formed in the display area naturally; and the deformable film layer is removed from the display substrate. Therefore,the yield of the display substrate is improved; and the narrow frame of the display device is realized.
