An organic light emitting diode array substrate, a preparation method therefor, and a touch display device. The array substrate comprises: a first metal layer pattern, a transparent conductive layer pattern, and an insulation layer pattern located between the first metal layer pattern and transparent conductive layer pattern. The first metal layer pattern comprises metal bridge lines (4). The transparent conductive pattern comprises an anode (5), multiple first electrode (7) extending along a first direction, and multiple second electrode (6) extending along a second direction. Each first electrode (7) comprises multiple first sub electrodes (71), and each first sub electrode (71) is electrically connected to one corresponding metal bridge line (4). In the array substrate, the first electrode (7), the second electrode (6) and the anode (5) of the organic light emitting diode are formed on a same layer, and multiple sub electrodes (71) are electrically connected by means of the metal bridge lines (4) so as to
