An OLED display device and manufacturing method thereof are provided. The method comprises: forming an array comprising first electrodes on a base substrate, with an area to which the first electrodes correspond being a display area; forming pixel defining layers respectively between the first electrodes so that a width of a cross section of each pixel defining layer is relatively larger at a middle portion and reduced gradually towards an upper portion and a lower portion; forming organic light-emitting layers respectively on the first electrodes between the pixel defining layers; and at least forming a second electrode which is at least provided on the organic light-emitting layers. The OLED display device made in this method can minimize the coffee ring effect of the organic light-emitting layers, avoid the layer-broken phenomenon occurring to the second electrode, and thus improve the display quality and save the material for the second electrode.
A method for manufacturing an organic light-emitting diode (OLED) display device comprising:
An organic light-emitting diode (OLED) display device comprising an array of first electrodes, pixel defining layers, organic light-emitting layers and a second electrode, wherein the pixel defining layers are respectively arranged between the first electrodes, and the organic light-emitting layers and the second electrode are successively arranged on the array of first electrodes, and a width of a cross section of each pixel defining layer is relatively larger at a middle portion and reduced successively towards an upper portion and towards a lower portion.
A display apparatus comprising an OLED display device, wherein the OLED display device comprises an array of first electrodes, pixel defining layers, organic light-emitting layers and a second electrode, the pixel defining layers are respectively arranged between the first electrodes, the organic light-emitting layers and the second electrode are successively arranged on the array of first electrodes, and a width of a cross section of each pixel defining layer is relatively larger at a middle portion and reduced successively towards an upper portion and towards a lower portion.
