Provided is a laminate which can not only control the amount of external light transmitted, but can also be used as a mirror. A laminate 1 comprises: a first liquid crystal member 100; a reflection type polarizing member 200; and a second liquid crystal member 300. The first liquid crystal member has first liquid crystal cells with changing orientation states, and a first absorption type polarizing member. The first liquid crystal cells can be switched: between a mode where one type of polarized light of the incident light is blocked and the other type of polarized light is transmitted, and a mode where one type of polarized light of the incident light is blocked and the other type of polarized light is shifted and then transmitted; between a mode where the incident light is transmitted as-is, and a mode where one type of the polarized light is blocked and the other type of polarized light is transmitted; and between a mode where one type of polarized light of the incident light is blocked and the other type of polarized light is transmitted, and a mode where one type of polarized light of the incident light is transmitted and the other type of polarized light is blocked. The reflection type polarizing member receives the light transmitted by the first liquid crystal member, transmits one type of polarized light of the incident light, and reflects the other type of polarized light. The second liquid crystal member has second liquid crystal cells with changing orientation states, and a second absorption type polarizing member. When the reflection type polarizing member has transmitted polarized light, the second liquid crystal cells can be switched between a mode where the polarized light is blocked and a mode where the polarized light is transmitted.

A pressure-sensitive adhesive and a liquid crystal cell including the same are disclosed herein. In some embodiments, a pressure-sensitive adhesive having a storage elastic modulus of 700 kPa or more at a temperature of 25° C. and a frequency of 6 rad/sec, and a gel fraction of 35% or more, wherein the gel fraction is defined by Equation 1:

B/A×100  [Equation 1]

wherein, A is an initial mass (g) of the pressure-sensitive adhesive, B is a mass (g) of an insoluble content after the pressure-sensitive adhesive is immersed in a solvent at 60° C. for 24 hours and then dried at 150° C. for 30 minutes. The press-sensitive adhesive is advantageous for implementation into a flexible element between upper and lower substrates of a liquid crystal cell, and providing excellent electro-optical properties and appearance uniformity by minimizing defects.

A method for improving readability of a display inside a motorized object comprises applying a polarization means on a side window of a motorized object, wherein an ambient incident light ray comes through the side window and is reflected by a surface of a display inside the motorized object to form a reflected light ray, and substantially filtering out display incident light S-polarization and allowing display incident light P-polarization to pass through. The polarization means has a linear polarization reflecting or absorbing direction that is substantially parallel to the plane of the surface of the display. A display readability enhancing system comprises the polarization means. When ambient light passes through the window and shines onto the interior display, the dominant light polarization is p-polarization for the interior display with minimum surface reflectivity upon reflecting from the interior display, resulting in good display visibility under strong ambient light conditions.

A light control sheet including a light control layer sandwiched between first and second orientation layers and including a polymer network in which domains are dispersed and filled with a liquid crystal composition including a liquid crystal molecule and a dichroic dye, a pair of transparent electrodes sandwiching the orientation layers, and a polarizing layer positioned on an opposite side of the first orientation layer to the light control layer. The light control layer has a transmittance that increases upon application of a driving voltage to the pair of transparent electrodes. When the driving voltage is not applied between the transparent electrodes, the orientation layers orient the liquid crystal molecule and the dichroic dye horizontally to the orientation layers and orient an orient absorption ax of the dichroic dye to cross an absorption axis of the polarizing layer as viewed in a thickness direction of the light control layer.
