    Abstract: A liquid crystal display panel (100A, 100B) includes a transverse electric field mode liquid crystal cell (10), a first polarizing plate (22A, 22B) disposed on a back surface side of the liquid crystal cell (10), and a second polarizing plate (24A, 24B) disposed on a viewer's side of the liquid crystal cell (10). A liquid crystal layer (18) contains a nematic liquid crystal whose dielectric anisotropy is negative. The liquid crystal layer (18) has And of less than 550 nm, where Δn is the birefringent index of the nematic liquid crystal and d is the thickness of the liquid crystal layer. The liquid crystal layer (18) is in a twist alignment state when no voltage is applied. When polarized light whose Stokes parameter S3 takes on an absolute value |S3| of 1.00 enters the liquid crystal layer (18), |S3| of polarized light having perpendicularly passed through the liquid crystal layer (18) is 0.85 or greater. The first polarizing plate (22A, 22B) and the second polarizing plate (24A, 24B) are circularly polarizing plates or elliptically polarizing plates whose ellipticity is 0.422 or greater.

    Abstract: The present invention provides a mirror display that can suppress warp of a half mirror plate with a reflective polarizer under heat to prevent distortion of a reflected image in a mirror mode. The mirror display of the present invention includes a half mirror plate that includes a first reflective polarizer and a first base material, a display device, and a warp-suppressing member that suppresses shrinking of the first reflective polarizer under heat. The first reflective polarizer and the first base material are integrated, and the display device is disposed on the back surface side of the half mirror plate.
