    Abstract: A transparent panel is provided. The transparent panel includes a polarization plate, a transparent diffusion plate which is disposed on one side of the polarization plate and is configured to transmit light incident from a side of the polarization plate and to reflect and diffuse a light incident from an opposite side of the polarization plate, a ¼ wavelength plate which is disposed on one side of the transparent diffusion plate and is configured to convert a polarization direction of an incident light, and a lens part which is disposed on one side of the ¼ wavelength plate. The lens part includes a lens array comprising a birefringent material having different refractive indexes according to a polarization direction of an incident light, and a refractive index alignment member configured to transmit or refract the light according to a polarization direction of a light that penetrates the lens array.
