Abstract:
Provided are a liquid crystal display device that suppresses occurrence of drop marks during production without degrading various properties, such as dielectric anisotropy, viscosity, nematic phase upper limit temperature, rotational viscosity (γ1), and ghosting property, and a method for producing the liquid crystal display device.A liquid crystal display device 10 of the present invention includes a liquid crystal composition layer 13 sandwiched between a first substrate 11 and a second substrate 12 and vertical alignment films 16 and 17 that contain a polymer of a polymerizable compound having a polyimide skeleton as a main chain and a crosslinkable functional group as a side chain. The liquid crystal composition constituting the liquid crystal composition layer 13 contains compounds represented by general formulae (I) and (II).
