Title: OLED DISPLAY UNIT AND MANUFACTURING METHOD THEREFOR
Abstract:
An OLED display unit and a manufacturing method therefor. The OLED display unit comprises a first electrode (10), a luminescent material layer (20), a second electrode (30) and an auxiliary electrode (40), wherein the auxiliary electrode (40) is arranged below the second electrode (30), is manufactured and formed prior to the luminescent material layer (20) and is in communication with the second electrode so as to reduce the impedance of the second electrode (30). The OLED display unit can reduce or eliminate a voltage drop produced by a wire resistance of a cathode in the case of a large area, thereby avoiding a power consumption increase caused by non-uniform luminescence.
