An organic light-emitting diode (OLED) display panel is provided, including an array layer. The array layer includes a first source electrode and a second source electrode that are disposed in contact with each other, and a first drain electrode and a second drain electrode that are disposed in contact with each other. The first source electrode and the first drain electrode are in contact with an active layer through via holes. The first source/drain electrode and the second source/drain electrode are disposed in contact with each other, thereby reducing a probability of abnormal via holes in a source/drain region and facilitating wiring in the source/drain region.
