Abstract

The invention discloses a display panel and a display device, capable of improving light conversion efficiency of the display panel. The display panel comprises an array substrate and a color film substrate which are oppositely arranged as well as a liquid crystal layer between the array substrate and the color film substrate, wherein a quantum dot excitation layer is arranged on the color film substrate; an upper polarizing layer is arranged between the color film substrate and the liquid crystal layer; a lower polarizing layer is arranged on one surface, not adjacent to the liquid crystal layer, of the array substrate; and through the upper polarizing layer, linearly polarized light transmitted from the lower polarizing layer can reach the quantum dot excitation layer by keeping the state of the linearly polarized light.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Quantum Dots (QD), also known as nanocrystals, are nanoparticles composed of II-VI or III-V elements. The particle size of quantum dots is generally between 1 and 20 nm. Since electrons and holes are quantum-confined, the continuous energy band structure becomes a discrete energy level structure with molecular characteristics, and can emit fluorescence after being excited. The emission spectrum of quantum dots can be controlled by changing the size of quantum dots. By changing the size and chemical composition of quantum dots, the emission spectrum can cover the entire visible light region. Taking cadmium telluride (CdTe) quantum dots as an example, when its particle size grows from 2.5nm to 4.0nm, their emission wavelength can be red-shifted from 510nm to 660nm. [0003] Quantum dots have high light c...
