Abstract

Embodiments of the present application discloses a display panel. A thin-film transistor layer includes a first stacking structure and a second stacking structure. The first stacking structure and the second stacking structure are provided corresponding to a same opening. The first stacking structure includes conductive layers and insulating layers. The second stacking structure includes a compensation layer and insulating layers. A number of the conductive layers of the first stacking structure is greater than a number of the conductive layers of the second stacking structure. The compensation layer is used to increase a height of the second stacking structure. The planarization layer covers the thin-film transistor layer.
