The optical laminate includes, in order, at least a first light absorption anisotropic layer, a refractive index anisotropic layer formed of a one or more layers that contain a liquid crystal compound having a twisted structure, and a second light absorption anisotropic layer, in which the first light absorption anisotropic layer and the second light absorption anisotropic layer contain an anisotropic absorbing material and each have an absorption axis that is aligned at an angle of 60° to 90° with respect to a film surface.

A projection type transparent display includes a polarization modulator and a reflective layer. The polarization modulator is stacked in sequence by a linear polarizer, a liquid crystal layer and a phase retarder. The reflective layer is stacked on the phase retarder. A projection light is incident on the linear polarizer to form a linearly polarized light. The liquid crystal layer changes a polarization direction of the linearly polarized light. Two kinds of linearly polarized projection lights with polarization directions orthogonal to each other are respectively formed and pass through the phase retarder to respectively form two kinds of circularly polarized projection lights with opposite rotation directions. A background light is incident on the reflective layer. A circularly polarized background light with the same spiral direction is reflected, and the circularly polarized background light opposite to the spiral direction passes through the reflective layer and is incident on the polarization modulator.

The present application provides a transmittance-variable device, which can be applied to various applications without causing problems such as a crosstalk phenomenon, a rainbow phenomenon or a mirroring phenomenon, while having excellent transmittance-variable characteristics.

According to one embodiment, a display device includes a first viewing angle control panel including a first liquid crystal molecule, a second viewing angle control panel including a second liquid crystal molecule, and a polarization axis rotating element. An initial alignment direction of the first liquid crystal molecule is substantially orthogonal to an initial alignment direction of the second liquid crystal molecule. A second polarization component transmitted through the first viewing angle control panel includes a second polarization axis. A third polarization component transmitted through the second viewing angle control panel includes a third polarization axis. The polarization axis rotating element rotates the third polarization axis to align the third polarization axis with the second polarization axis.

A one-way glass with switching modes includes an absorbing layer located on a weak light side, a reflecting layer located on an intense light side, and a converting layer stacked between the absorbing layer and the reflecting layer. The absorbing layer absorbs first polarized light and allows second polarized light to pass through. The reflecting layer reflects the first polarized light and allows the second polarized light to pass through. Unpolarized light incident from the weak light side or from the intense light side is respectively converted into the polarized light. During the process of gradually adjusting the converting layer from a twisted state to a vertical state, rotated angles of polarization directions of the first polarized light and the second polarized light gradually decrease.
