Abstract
A transparent panel includes a first substrate, a second substrate, and a plurality of pixel regions. The second substrate is opposite to the first substrate. The plurality of pixel regions are between the first substrate and the second substrate. Each of the pixel regions includes a first region and a second region. A scattering degree of the first region is greater than a scattering degree of the second region. An area ratio of the first region to the second region in a pixel region increases as a distance between the pixel region and at least one side of the transparent panel increases.
