Liquid crystal display device's substrate, liquid crystal display device including the same, and manufacturing method of the same
View Patent ↗The invention relates to a manufacturing method of a liquid crystal display device in which an alignment direction of a liquid crystal molecule at the time of driving is regulated by using a polymer, and has an object to provide a manufacturing method of a liquid crystal display device in which excellent display characteristics can be obtained. A liquid crystal layer containing a polymerizable component capable of being polymerized by light is sealed between two substrates arranged to be opposite to each other, the polymerizable component is polymerized by irradiation of light under a predetermined light irradiation condition while a voltage is applied to the liquid crystal layer under a predetermined voltage application condition, and when a pre-tilt angle of a liquid crystal molecule and/or an alignment direction at a time of driving is regulated, at least one of the voltage application condition and the light irradiation condition is changed for each region.
1. A liquid crystal display device's substrate comprising:
a substrate disposed to be opposite to another substrate, between which a liquid crystal layer containing a polymer polymerized by ultraviolet light to regulate a pre-tilt angle of a liquid crystal molecule and/or an alignment direction at a time of driving is sandwiched;
color filter resin layers formed on the substrate; and
pixel regions arranged in matrix form on the substrate and having different transmission factors of the ultraviolet light for respective colors of the color filter resin layers.
2. A liquid crystal display device's substrate according to claim 1 , wherein when the transmission factor of a red pixel is Tr, the transmission factor of a green pixel is Tg, and the transmission factor of a blue pixel is Tb, the transmission factors satisfy an inequality of Tr>Tg>Tb.
3. A liquid crystal display device's substrate according to claim 1 , wherein formation materials of the color filter resin layers are different among the respective colors.
