Embodiments of this application provide a display panel, a preparation method therefor, and a terminal. The display panel includes a substrate, a first organic light emitting diode and a second organic light emitting diode that are adjacent, a pixel define layer, and a common layer. The first organic light emitting diode and the second organic light emitting diode respectively include a first anode and a second anode. The common layer includes a first part located on the first anode, a second part located on the second anode, and a blocking part that is located on the pixel define layer and that is formed due to the pixel define layer.
