Abstract: The present disclosure relates to a light shutter panel and a transparent display apparatus having the same. The light shutter panel comprises: a first light shutter panel and a second light shutter panel. Each of the first and second light shutter panels includes: a lower electrode plate, an upper electrode plate, a shutter layer, transparent spacers and a black ink. The lower electrode plate and the upper electrode plate are attached as facing each other. The shutter layer is disposed between the lower electrode plate and the upper electrode plate. The shutter layer includes a maximum light transmitting portion, a minimum light blocking portion, an ink storage portion and an electric field guide. The electric field guide is disposed between the ink storage portions. The transparent spacers maintain the gap between the lower electrode plate and the upper electrode plate. The black ink is filled into the ink storage portion.
