Abstract
Provided are an OLED display panel and a preparation method thereof. The OLED display panel includes a light-shielding layer, a planarization layer, an anode layer, a light-emitting material layer, and a cathode layer. The light-shielding layer includes a light-shielding structure and a first structure. The anode layer includes an anode and a third structure. The first structure and the third structure disposed in a non-light-emitting region of the OLED display panel are electrically connected. The light-emitting material layer is on a side of the anode layer away from a substrate. The cathode layer is on a side of the light-emitting material layer away from the substrate. In the non-light-emitting region, the first structure is connected to a fixed value voltage. The light-emitting material layer is provided with a first via hole. The cathode layer is electrically connected to the third structure through the first via hole.
