Abstract
Embodiments of the present invention disclose a display panel and a display apparatus so as to increase the optical conversion efficiency of the display panel. The display panel comprises: an array substrate and a color filter substrate which are arranged oppositely; a liquid crystal layer arranged between the array substrate and the color filter substrate; an upper polarizing layer provided between the color filter substrate and the liquid crystal layer; and a quantum dot excitation layer provided on the color substrate, wherein the upper polarizing layer is configured such that a first linearly polarized light transmitted through the upper polarizing layer irradiates on the quantum dot excitation layer. By disposing the upper polarizing layer between the color filter substrate and the liquid crystal layer, a first linearly polarized light transmitted through the upper polarizing layer arrives at the quantum dot excitation layer, then the quantum dot excitation layer is excited by the first linearly polarized light and emits scattered light, the optical conversion efficiency of the display panel is thus increased.
