Provided is a liquid crystal display device including: a liquid crystal cell () including a first substrate (), a second substrate (), and a liquid crystal layer () sealed between the first substrate and the second substrate; a first polarization member () for transmitting light in a predetermined polarization direction; and a second polarization member () for transmitting light in another polarization direction which is orthogonal to the predetermined polarization direction. At least one of the first polarization member and the second polarization member includes a multilayer thin film polarizer including a plurality of thin film polarizers which are stacked so that transmission axes of the plurality of thin film polarizers are aligned. The multilayer thin film polarizer includes a thin film polarizer formed in a predetermined film thickness by coating with dye molecules which are aligned by a shear stress.

Abrasive grains have mainly grains with a roundness of 0.50 or more and 0.75 or less, where the roundness is defined as the ratio of the circumference of a circle having the same area as that of a grain to the perimeter of that grain. An abrasive has the abrasive grains and at least one of an oxidizer, an oxide solution, an abrasive grain dispersion agent and a basic compound. An abrasive solution has the abrasive grains and water or hydrophilic substance.
