1. A transparent display apparatus comprising:
a first substrate having a first surface;
a second substrate having a second surface on an opposite side of the first surface;
a display layer arranged between the first substrate and the second substrate and having pixels that can transition between a transparent state transmitting background light and a non-transparent state displaying an image;
a display region provided in a region where the first substrate, the second substrate, and the display layer overlap;
a controller controlling a state of the pixels of the display layer; and
the image displayed in the display region from a side of the first surface and a background on a side of the second surface being visible, and the image displayed in the display region from a side of the second surface and the background on the first surface side being visible,
wherein the controller controls a state of a first lighting that illuminates an inside of a first space in causing the display layer to display the image toward a first user in the first space on the first surface side, and
wherein a light from the first lighting reaches the first space without passing through the first substrate and the second substrate.
