The display panel includes a first substrate, a second substrate, a display material layer, an active component layer, a color filter layer and a light source. The display material layer is disposed between the first substrate and the second substrate. The active component layer and the color filter layer are disposed between the first substrate and the display material layer. The light source is disposed on one side of the second substrate, and emits light. The light passes through the second substrate and the color filter layer and arrives at the first substrate, and is reflected by the first substrate and then enters the color filter layer. The light further passes through the color filter layer, enters the display material layer, passes through the display material layer, and is outputted to the exterior."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Display panel and rollable display device","description":"The present disclosure relates to a display panel.
