Abstract
A transparent display device including a liquid crystal panel is provided. The liquid crystal panel includes a color filter substrate, an array substrate, a liquid crystal layer, a first polarizer and a second polarizer. The first polarizer is disposed on a side of the color filter substrate far from the liquid crystal layer. The second polarizer is disposed on a side of the array substrate far from the liquid crystal layer. The color filter substrate includes a transparent base, and a color filter formed on the transparent base. The color filter includes compound pixel regions, wherein each of the compound pixel regions has color sub-pixel regions and a transparent sub-pixel region. The second polarizer includes a non-polarized pattern spatially corresponding to the transparent sub-pixel region in the color filter, after a light passing through the non-polarized pattern, the polarization state remains unchanged.
