Abstract: A display panel includes a light source section, a light guide section, a liquid crystal layer, a partition section, a display section, and a diffraction section. The light source section emits plural lights of different colors. The light emitted from the light source section enters the light guide section. The light that has passed through the light guide section enters the liquid crystal layer. The partition section partitions the liquid crystal layer into plural pixel regions. The partition section includes plural scanning lines and plural black matrices arranged at intervals in an intersecting direction that intersects with a thickness direction of the light guide section. An image formed by the light emitted from the plural pixel regions is displayed on the display section. The diffraction section diffracts the plural lights that have entered the light guide section from the light source section.

Abstract: A transparent display apparatus includes a first substrate having a first surface, a second substrate having a second surface, a display layer having pixels, a display region provided in a region where the first substrate, the second substrate, and the display layer overlap, a controller, and a sensor device for detecting a viewpoint of the first user. The controller displays a plurality of individually selectable selection images toward the first user in the display region (screen), determines a gaze image, which is the selection image gazed by the first user, from detection information of the sensor device, and controls a state of pixels so that the corresponding image based on the gaze image is displayed to the second user on an opposite side to the first user.
