Abstract
An OLED display device is disclosed, and the metal connection electrode is connected to the auxiliary electrode through a recessed hole; the recessed hole forms a first cavity and a second cavity communicating with each other, and the first cavity extends from an edge line of the second cavity away from the pixel electrode in the same direction; the pixel definition layer is above the array substrate, and reserved with grooves corresponding to the recessed holes and the pixel electrodes; an OLED semiconductor layer on the pixel definition layer covers on the pixel electrode and the metal connection electrode, and also extends into the first cavity to be connected with the auxiliary electrode; a cathode is on the OLED semiconductor layer, and extends into the first cavity to be connected with the auxiliary electrode, and is in a discontinuous connection state with the recessed hole as a breakpoint.
