Polarizing Device, Liquid Crystal Display Device and Manufacturing Method Thereof

摘要

The present invention discloses a polarizing device, a liquid crystal display device and a manufacturing method thereof. The polarizing device comprises: a first support layer, a polarizing layer used to output linear polarized light, and a conversion layer with phase delay of m/4 wavelength. The m is an odd number larger than zero. The first support layer, the polarizing layer, and the conversion layer are staked sequentially. The angle θ between the optical axis of the conversion layer and the polarization axis of the polarizing layer are n*90°+45°, the n being an integer not less than zero. In this way, the present invention can change the polarization state of the emitted light of the liquid crystal display device without significantly increasing the cost of production, which can protect the human eye.
