Abstract: According to a liquid crystal display panel and a display device in the present disclosure, since at least one of a first polarizer and a second polarizer has a light scattering structure, polarized light of corresponding colors transmitted by sub-pixel units with different colors in a liquid crystal display structure can be uniformly diffused by the light scattering structure. That is to say, the light scattering structure plays a role for uniformly mixing the polarized light of different colors. Therefore, the rainbow pattern phenomenon is effectively improved or even eliminated, and the display quality is improved.
