Abstract

A display panel including a first substrate, a second substrate, a first alignment layer, a second alignment layer, a liquid crystal layer, a first electrode layer and a second electrode layer is provided. The first alignment layer and the second alignment layer are respectively disposed on the first substrate and the second substrate. The first electrode layer and the second electrode layer are used to drive a plurality of liquid crystal molecules of the liquid crystal layer. While the first electrode layer and the second electrode layer are deactivated, a molecular long axis of each liquid crystal molecule against a substrate surface of the first substrate at an inclined angle is greater than 9 degrees. An orthographic projection of the molecular long axis on the first substrate or the second substrate is parallel to an alignment direction of the first alignment layer or the second alignment layer.
