A liquid crystal cell is optically compensated accurately, suppresses a color shift depending on a viewing angle direction at the time of high contrast and black display, and sufficiently changes in Re and Rth with respect to a change in environmental humidity. Provided are an optical compensation film for polarizing plate, a polarizing plate using the same, and a liquid crystal display device. An optical system comprising at least compound A having a plurality of hydrogen bonding groups in one molecule and at least one of compounds B represented by general formulas (I) to (III). Such as a compensation film. [Selection figure] None |
