LIGHT SHIELD APPARATUS, METHOD OF FABRICATING THE LIGHT SHIELD APPARATUS, AND TRANSPARENT DISPLAY DEVICE INCLUDING THE LIGHT SHIELD APPRATUS

摘要

According to an embodiment of the present invention, the present invention relates to a light blocking device which can transmit or block light by using a plurality of PDLC layers, a method for manufacturing the light blocking device, and a transparent display device including the light blocking device. According to an embodiment of the present invention, the light blocking device comprises: first and second substrates which face each other; a first electrode disposed on the first substrate; a second electrode disposed on the second substrate; and first and second polymer dispersed liquid crystal layers disposed between the first and second electrodes. The first polymer dispersed liquid crystal layer includes first droplets having first liquid crystals, and the second polymer dispersed liquid crystal layer includes second droplets having second liquid crystals and first dichroic dyes.
