| description | A light controlling apparatus, a method of fabricating the light controlling apparatus, and a transparent display device including the light controlling apparatus are disclosed, in which light may be transmitted or shielded using a polymer dispersed liquid crystal (PDLC) layer and a guest-host liquid crystal (GHLC) layer, where the guest-host liquid crystal layer includes dichroic dyes. The light controlling apparatus (100) includes first and second substrates (110, 150) facing each other; a first electrode (120) on the first substrate (110); a second electrode (140) on the second substrate (150); and a polymer dispersed liquid crystal (PDLC) layer (131) and a guest-host liquid crystal (GHLC) layer (132) between the first electrode (120) and the second electrode (140), wherein the PDLC layer (131) includes droplets (131b) having first liquid crystals (131c), and the GHLC layer (132) includes second liquid crystals (132a) and dichroic dyes (132b). |
