Abstract: Provided are a polarizing plate including a polarizing layer containing a lyotropic liquid crystal compound and capable of achieving uniform polarization properties over a large area, and a display device equipped with the polarizing plate. The polarizing plate includes: an alignment film; and a polarizing layer on the alignment film. The alignment film contains an alignment film polymer, has a static contact angle with water of 60° or smaller, and has a slow axis. The polarizing layer contains a lyotropic liquid crystal compound and has an absorption axis parallel to the above slow axis. The lyotropic liquid crystal compound is preferably dichroic.
