摘要： A liquid crystal display device which can exhibit a blue phase stably is manufactured. A first substrate and a second substrate are attached by a sealant interposing a liquid crystal layer comprising a liquid crystal composition therebetween, an alignment state of the liquid crystal layer is set to be an isotropic phase by heat treatment, the liquid crystal layer is irradiated with light so as to perform polymer stabilization treatment on the liquid crystal layer, and an alignment state of the liquid crystal layer is changed from an isotropic phase to a blue phase in the light irradiation. Thus, a liquid crystal display device which suppresses a defect which shows an alignment state other than a blue phase (an alignment defect) is manufactured.

摘要： A polarizer in which parallel transmittance TP is increased and crossed transmittance TC is provided. Instead of arranging a plurality of all metal wires on one plane, a plurality of metal wires is separately formed on at least two different parallel planes, and adjacent meal wires among the plurality of metal wires are staggered in the polarizer. The heights of a first group of metal wires formed on a first plane and a second group of metal wires formed on a second plane, from a surface of the light-transmitting substrate are different. Further, a metal wire of the second group is provided to be more distant from the light-transmitting substrate than the first group of metal wires by distance D, and the distance D is smaller than the thickness of the first group of metal wires.

摘要： It is an object of the present invention to suppress light leakage in a dark state which is generated by rubbing treatment. A liquid crystal material containing an ultraviolet curable liquid crystalline monomer at a concentration of more than 0 wt % and not more than 1.0 wt % is used for a liquid crystal layer, and the liquid crystal layer is irradiated with ultraviolet rays. By applying such a liquid crystal layer to a liquid crystal display device, light leakage in a dark state can be suppressed, and the black display can be improved. Therefore, a liquid crystal display device with an excellent contrast and high display quality can be obtained.

摘要： External light is reflected due to a difference in refractive indices of a black matrix and a glass substrate. When the black matrix is a black resin, there is a difference in refractive indices of the black resin and a first substrate. Also, there is a difference in refractive indices of the colored layer and the first substrate. Therefore, external light is slightly reflected. There is a problem in that the reflected light reduces contrast. A structure in which one polarizing element having dichroism is interposed between a pair of substrates is employed, and a light interference layer is provided between a color filter and a glass substrate, whereby a difference in refractive indices is moderated to reduce light reflection.

摘要： A liquid crystal layer including a polymerizable monomer and a liquid crystal composition exhibiting a blue phase is provided between a first substrate and a second substrate which are bonded to each other with a sealant. Further, the sealant and part of the liquid crystal layer are covered by a light shield and a first light irradiation treatment is performed on the liquid crystal layer with use of the light shield as a mask, whereby a first region in which the polymerizable monomer is polymerized is formed. Furthermore, a second light irradiation treatment is performed on the liquid crystal layer after the light shield is removed, whereby a second region having a lower degree of polymerization of the polymerizable monomer than the first region is formed.
