Abstract

A manufacturing method of an array substrate of an OLED display device is provided. Active areas of a first thin film transistor Tand a second thin film transistor Tare formed by a first mask; channel doping areas, source electrode doping areas and drain electrode doping areas of Tand Tare formed by a second mask; gate electrodes of Tand Tare formed by a third mask; vias are formed by a fourth mask; source electrodes and drain electrodes of Tand T, a data line and a pixel electrode are formed by a fifth mask. The manufacturing method can simplify the process steps.
