Abstract: A liquid crystal display panel (100A) includes a first polarizing plate (22) and a first phase difference plate (32a) disposed on an observer side, and a second polarizing plate (24) and a second phase difference plate (34a) disposed on a back surface side. Δnd of a liquid crystal layer having a homogeneous alignment when no electrical field is applied is 360 nm or greater and 490 nm or less, and an in-plane retardation R1 of the first phase difference plate is 100 nm or greater and 160 nm or less. A thickness direction retardation of at least one of the first and second phase difference plates has a negative value. The slow axes of the first and second phase difference plates are substantially parallel to each other and substantially orthogonal to an azimuthal direction of the liquid crystal director.

Abstract: A mirror display system that enables simultaneous perception of a mirror image and a video image with suppressed uncomfortable feeling includes a half mirror plate including a half mirror layer; a 3D display device; and a control unit being configured to supply a video signal to the 3D display device. The 3D display device is disposed on the back surface side of the half mirror plate and is configured to display, by the video signal, a video image for the left eye and a video image for the right eye that give a parallax on a display surface of the 3D display device. The parallax is set such that a fused video image of the video image for the left eye and the video image for the right eye is perceived on the back surface side behind the display surface of the 3D display device.

Abstract: A display device capable of emitting sufficient fluorescence is provided without an increase in the thickness of the liquid crystal layer. The device includes: a fluorescent emission layer (23) having fluorescent pigment molecules that absorb light to emit fluorescence; and a liquid crystal layer (4) capable of switching between a transparent state and a scattering state. The fluorescent pigment molecules are dichroic fluorescent pigment molecules (23a) with different emission intensities depending on the direction of emission. The dichroic fluorescent pigment molecules (23a) in the fluorescent emission layer (23) are oriented so as to have transition dipole moments with the same direction.
