Abstract
(EN)
Disclosed are a polarizing structure and a display panel. The polarizing structure comprises a support film (100), an optical compensation film (200), a polarizing film (300) and a phase compensation film (400) arranged in a stacked manner and in sequence, wherein the support film (100) comprises a light incident face (100A) and a light emergent face (100B), and the light emergent face (100B) is provided with a plurality of grooves (101); and the optical compensation film (200) is provided with a plurality of protruding structures (201) matching the grooves (101), and each of the protruding structures (201) is accommodated in the corresponding groove (101), a width of each of the protruding structures (201) is less than or close to a wavelength of incident light, and the refractive index of the support film (100) is greater than that of the optical compensation film (200).
