Abstract
A micro-reflecting layer of the present invention used for polarized plates and display device comprises a transparent resin layer and a plurality of micro-reflecting particles. The micro-reflecting particles are uniformly implanted into the transparent resin, and light from an external source partially passes through the micro-reflecting particles and partially is reflected by the micro-reflecting particles to display an image. Furthermore, a plurality of optical diffusing particles is also added into the micro-reflecting layer so as to uniformly diffuse the light in the micro-reflecting layer.
