Abstract

A display panel (20) and a display device. A display panel (20), comprising a first substrate (21), a second substrate (22), and a liquid crystal layer (23) located between the first substrate (21) and the second substrate (22), the first substrate (21) A plurality of pixel regions (SP) are formed on the liquid crystal layer (23), the liquid crystal layer (23) contains liquid crystal molecules (231), the first alignment layer (219) is arranged on the first substrate (21) close to the liquid crystal layer (23), and the second substrate ( 22) is provided with a second alignment layer (224) close to the liquid crystal layer (23), and a polarizer (223) is provided on the outside of the second substrate (22). The polarizer (223) has a light transmission axis (P1), and the first The first alignment direction (X1) of the alignment layer (219) and the second alignment direction (X2) of the second alignment layer (224) are antiparallel, and both are in the direction of the light transmission axis (P1) of the polarizer (223) Vertically, the liquid crystal layer (23) is doped with quantum rods (232), and in each pixel region (SP), quantum rods (232) with different sizes are mixed with liquid crystal molecules (231), and the liquid crystal molecules ( 231) are arranged along the first alignment direction (X1) and the second alignment direction (X2), the alignment direction of the quantum rods (232) is consistent with the liquid crystal molecules (231), and the quantum rods (232) can convert the incident non-polarized light Converts to linearly polarized light in the same direction as its long axis.

Description
