Abstract
A display panel and a manufacturing method thereof, and a display apparatus are provided. The display panel is provided with a function hole, the display panel includes a substrate; and a laminated structure for the function hole formed on a substrate; the laminated structure includes a light blocking layer, a semi-transparent layer and a shadow removing layer, the shadow removing layer is provided between the light blocking layer and the semi-transparent layer, and at least entirely covers the function hole. For the display panel, the L value of the semi-transparent ink or blacking ink at the function hole is increased by additionally providing the shadow removing layer at the function hole, reducing the chromatic aberration between the screen printed semi-transparent layer and the light blocking layer at the function hole.
