Abstract

The present disclosure provides an optical assembly, a liquid crystal display device, and an electronic equipment. The optical assembly includes: a linear polarizer, a half-wave plate, and a quarter-wave plate stacked in sequence. An absorption axis of the linear polarizer is substantially perpendicular to a first direction, and the first direction is parallel to a surface of the linear polarizer; an angle between an in-plane slow axis of the half-wave plate and the first direction is in a range of 100° to 110°; an angle between an in-plane slow axis of the quarter-wave plate and the first direction is in a range of 160° to 170°.
