Abstract
A display panel includes a first inorganic capping layer (INOCL) in a non-displaying area (AND) of a substrate, a first electrode in the AND formed on the first INOCL, an organic capping layer (OCL) on the substrate overlapping at least a portion of the first electrode, and a first dam structure in the AND positioned between a first lateral surface of the substrate and the OCL in top view. A first distance H is between the top surfaces of the first INOCL and the OCL in a normal direction of the substrate. The first dam structure has a first maximum dam height Hdam and a dam width Wdam. A second distance Lsr is a minimum distance from a third lateral surface of the first dam structure to a second lateral surface of the first electrode, wherein H, Lsr, Hdam and Wdam conform to the equation: H×(0.1870−Wdam/(2.46×Lsr))≤Hdam≤H×(0.9548−Wdam/(44.26×Lsr)).
