We demonstrated a new transparent display consisting of an optically switchable polymer network liquid crystal and light sources. Optical switching between transparent and screen states was achieved through trans-cis photoisomerization of azobenzene. Furthermore, we improved screen reflectance by increasing the helical twisting power difference between the trans and cis states.
