Abstract

The present invention provides a polarizing device and an optical alignment device, including a polarizing unit and a mounting frame, and the polarizing unit includes a polarizing wire grid, a wire grid frame plate, and a wire grid adjustment unit. The wire grid frame plate is used to support the polarized wire grid, and the wire grid frame plate is rotated and installed on the installation frame with the normal direction of the polarized wire grid as the rotation axis, and the wire grid adjustment unit is The rotation of the wire grid frame plate provides the driving force, the rotation axis of the wire grid frame plate and the driving force point of the wire grid adjustment unit are located on a pair of opposite corners of the wire grid plane of the polarizing wire grid, solving The problem that the adjustment resolution of the existing polarizing device cannot meet the needs of actual use is solved.

Description

technical field [0001] The invention relates to the technical field of semiconductor manufacturing, in particular to a polarizing device and an optical alignment device. Background technique [0002] A liquid crystal display panel (LCD) generally includes two substrates (array substrate TFT, color filter substrate CF), a liquid crystal layer between the two substrates, and a polarizer outside the two substrates. In liquid crystal display technology, an electric field is generated in the liquid crystal layer by applying a voltage, thereby changing the twist angle of the liquid crystal molecules, and matching with the two polarizers on the outside of the upper and lower substrates to produce image display. [0003] However, in order to ensure the display effect of images, the liquid crystal molecules need to have an initial alignment direction, so an alignment film layer needs to be provided on the substrate, which can align the liquid crystals in a certain direction. That is...
