Abstract:
1. A reflective liquid crystal display panel comprising: a first substrate; a second substrate, disposed over the first substrate; a liquid crystal layer, disposed between the first substrate and the second substrate, wherein the liquid crystal layer is doped with an optical aligned material, an orientation of the optical aligned material doped liquid crystal layer is capable of being changed by a linear polarized light to show an image, and the orientation of the optical aligned material doped liquid crystal layer is capable of being restored by a circular polarized light to erase the image; a transflective film, disposed below the first substrate, wherein the transflective film allows the polarized light to pass through, and also for reflecting an external light; a retarder, disposed between the transflective film and the first substrate; and a polarizer, disposed on the second substrate, wherein the retarder has an optical axis, the polarizer has an absorption axis, and the optical axis makes an angle of 45° or an angle of 90° with the absorption axis.
