Abstract
A display panel includes a light-transmitting area and a display area including a first and a second display area, the first display area and the light-transmitting area constitute a transparent display area; the display area includes: a display substrate including a light-emitting area and a non-light-emitting area; a low refraction layer; a high refraction layer, the high refraction layer covering at least the light-emitting area and a side surface of the low refraction layer facing the light-emitting area; the refractive index of the high refraction layer is greater than that of the low refraction layer, the side surface of the low refraction layer facing the light-emitting area is in contact with the high refraction layer to form a total reflection interface, the total reflection interface is configured to allow the display light emitted from the light-emitting area and incident through the high refraction layer to perform total reflection.
