Abstract

The present disclosure relates to a display panel including a first substrate, a second substrate, and a liquid crystal layer between the first substrate and the second substrate. The display panel also includes a first polarized film and a first frame glue, and the first polarized film adheres to a surface of the first substrate facing toward the second substrate. The first frame glue connects between the first substrate and the second substrate such that a closed cell is formed cooperatively by the first substrate and the second substrate. The first polarized film and the liquid crystal layer are received within the closed cell. The present disclosure also relates to a liquid crystal display device. The first polarized film is isolated from external environment so as to enhance the stability of the first polarized film.
